  • Atmospheric Pressure Plasma Activation of Polymers and Composites for Adhesive Bonding: a Critical Review
    Atmospheric Pressure Plasma Activation of Polymers and Composites for Adhesive Bonding: A Critical Review Thomas S. Williams, Hang Yu and Robert F. Hicks* University of California at Los Angeles, Department of Chemical and Biomolecular Engineering, Boelter Hall Room 5531, Los Angeles, California 90095-1592 Abstract: A review is presented on the surface preparation of polymers and composites using atmospheric pressure plasmas. This is a promising technique for replacing traditional methods of surface preparation by abrasion. With suffi cient exposure to the plasma afterglow, polymer and composite surfaces are fully activated such that when bonded and cured with epoxy adhesives, they undergo 100% cohesive failure in the adhesive. Depending on the material, the lap shear strength and crack delamination resistance (GIC) can be increased several fold over that achieved by either solvent wiping or abrasion. In some cases, a plasma-responsive layer must be incorporated into the top resin layer of the composite to achieve maximum bond strength to the adhesive. Adhesion does not correlate well with water contact angle or surface roughness. Instead it correlates with the fraction of the polymer surface sites that are oxidized and converted into active functional groups, as determined by x-ray photoelectron spectroscopy and infrared spectroscopy. Keywords: Polymer, composite, epoxy, adhesion, bonding, atmospheric plasma, plasma activation 1 Introduction The strength of bonded joints is of great concern to the aerospace, automotive, medical device, and electronics industries [1]. Atmospheric pressure plasma acti- vation is rapidly gaining acceptance as a desirable method of surface preparation prior to bonding [1]. This technique provides an alternative to traditional methods of surface preparation by wet chemical cleaning and mechanical abrasion [1, 2].

This paper reviews plasma polymerization processes as surface modification (finishing) for textile applications. The dry and ecofriendly plasma technology aims at replacing wet-chemical process steps and adding new values to textile products. Characteristics of hydrocarbon, organosilicon, fluorocarbon, hydrophilic functional, monofunctional and ceramic coatings have been discussed to demonstrate their potential for textiles and fibers. Plasma technology requires adequate reactors for the continuous treatment of fabrics and fibers. To enable the optimization of plasma polymerization on batch reactors, questions of up-scaling are addressed to demonstrate the transfer to an industrial level. Both atmospheric and low pressure plasmas are considered regarding their effectiveness and efficiency.

  • Surface Modification of Polymer Substrates for Biomedical
    materials Review Surface Modification of Polymer Substrates for Biomedical Applications OldˇrichNedˇela,Petr Slepiˇcka* and Václav Švorˇcík Department of Solid State Engineering, University of Chemistry and Technology, 166 28 Prague, Czech Republic; [email protected] (O.N.); [email protected] (V.Š.) * Correspondence: [email protected]; Tel.: +420-220-44-5163 Received: 10 August 2017; Accepted: 18 September 2017; Published: 21 September 2017 Abstract: While polymers are widely utilized materials in the biomedical industry, they are rarely used in an unmodified state. Some kind of a surface treatment is often necessary to achieve properties suitable for specific applications. There are multiple methods of surface treatment, each with their own pros and cons, such as plasma and laser treatment, UV lamp modification, etching, grafting, metallization, ion sputtering and others. An appropriate treatment can change the physico-chemical properties of the surface of a polymer in a way that makes it attractive for a variety of biological compounds, or, on the contrary, makes the polymer exhibit antibacterial or cytotoxic properties, thus making the polymer usable in a variety of biomedical applications. This review examines four popular methods of polymer surface modification: laser treatment, ion implantation, plasma treatment and nanoparticle grafting. Surface treatment-induced changes of the physico-chemical properties, morphology, chemical composition and biocompatibility of a variety of polymer substrates are studied. Relevant biological methods are used to determine the influence of various surface treatments and grafting processes on the biocompatibility of the new surfaces—mammalian cell adhesion and proliferation is studied as well as other potential applications of the surface-treated polymer substrates in the biomedical industry.

Universidad 30, 28911 Leganés, Spain; [email protected] (J.A.); [email protected] (S.L.d.A.) * Correspondence: [email protected]; Tel.: +34-91-624-9401 Received: 17 October 2018; Accepted: 26 November 2018; Published: 26 November 2018 Abstract: Generally, polymeric materials present an issue related to their low surface energy: low painting ability. The main aim of this work is to improve the adhesion between polymeric surfaces (polydimethylsiloxane (PDMS), and acrylonitrile-butadiene-styrene (ABS)) and paints (epoxy (EP), and polyurethane (PU)-based). In order to increase adhesion, hydrophilic modification of surfaces by atmospheric pressure plasma torch treatment (APPT) was proposed. Furthermore, it can permit dissimilar joints, i.e., ABS with a metal joined by a silicone (based PDMS), to be painted. The surface modifications were characterized by measurements of surface energy and roughness. In addition, the effectiveness of the pre-treatment on improving paint adhesion was confirmed by scratch, cross-cut, and adhesion tests. Results showed the possibility of coating both ABS and PDMS with a PU-based paint when treated with plasma. As a novel result, polymer and metal panels joined by silicone were able to be painted with the PU paint. Keywords: polydimethylsiloxane; acrylonitrile-butadiene-styrene; atmospheric pressure plasma torch; epoxy paint; polyurethane paint; adhesion tests 1. Introduction Acrylonitrile-butadiene-styrene (ABS) and polydimethylsiloxane (PDMS) polymers are widely used, as they offer excellent intrinsic properties such as lightweight, high strength or chemical resistance, among others.

Initially, the plasma-treated samples were investigated using static contact angle Surface modification measurements, showing a progressive increase in wettability with increasing plasma activation time between 10 Surface functionalization and 40 s. Such an increase in wettability (and therefore increase in adhesive capabilities of the surfaces) was attributed to the creation of surface C-OH, C=O, and COOH groups. These surface-chemical modifications were characterized using x-ray photoelectron spectroscopy (XPS) and static secondary ion mass spectrometry (SSIMS). Surface radical densities were also shown to increase following plasma activation, having been quantifiedusing a radical scavenging method based on the molecule 2,2-diphenyl-1-picrylhydrazyl (DPPH). The samples were imaged and analyzed using scanning electron microscopy (SEM) and atomic force microscopy (AFM), to confirm that there had been no detectable alteration to the surface roughness or morphology.

  • Atmospheric Pressure Plasma As a Method for Improving Adhesive Bonding Authors THOMAS S
    TP14PUB43 Atmospheric Pressure Plasma as a Method for Improving Adhesive Bonding authors THOMAS S. WILLIAMS, HANG YU, RICHIE WOO, MIKHAIL GRIGORIEV, DICK CHENG, and ROBERT F. HICKS Aerospace Materials Processing LLC Redondo Beach, CA abstract Atmospheric pressure plasma treatment is an alternative surface preparation method for plastics and organic matrix composites prior to structural adhesive bonding. The atmospheric pressure plasmas are a promising technique for replacing traditional methods of surface preparation such as manual sanding, grit blasting, peel ply, or wet chemistry. All surfaces studied were converted from a hydrophobic state into a hydrophilic state with a water contact angle of <40°. Atomic force microscopy confirmed that plasma activation resulted in only minor changes to the composite surface structure. Characterization of the composite surfaces by X-ray photoelectron spectroscopy revealed an increase in oxygen content following plasma treatment. Lap shear testing showed that after plasma activation, the strength can be increased from ~50% up to several-fold over that achieved by either solvent wiping or abrasion depending on the material used. terms Plasma treatment, Surface preparation, Adhesive bonding, Plastics, Matrix composites conference Composites Manufacturing 2014 SME April 8-10, 2014 Covington, KY SME TECHNICAL PAPERS This Technical Paper may not be reproduced in whole or in part in any form without the express written permission of SME.

    ©2020 Published in 8th International Symposium on Innovative Technologies in Engineering and Science 23-25 October 2020 (ISITES2020 Bursa - Turkey) https://doi.org/10.33793/acperpro.03.01.77 Adhesion Imrovement with Plasma Surface Activation Between Aluminum Alloy Plates *1Ekrem Altuncu, 1Ayyuce Tecir and 2Onur Birbaşar *1 Sakarya University of Applied Sciences, Materials and Manufac.Tech. App. Research Center-SUMAR,Sakarya, Turkey 2 Assan Aluminum R&D Center, Kocaeli, Turkey Abstract Aluminum alloys are advantageous light metals in many respects. In the use of these alloys in the ship, aviation and automotive industries, bonding applications rather than welded joints or mechanical connections are preferred. Improving adhesion properties with various surface treatments applied to aluminum alloys is an important issue. Adhesive type, front surface treatments and surface activation techniques control adhesion strength. In this study, the effect of plasma surface treatment technology on adhesion strength was examined in detail. The water drop wetting ability of the alloys were examined, and then adhesion properties were compared with adhesion tests. It has been determined that plasma technology significantly increases the adhesion strength. Key words: Aluminum alloys, Adhesion, Surface Treatment, Plasma activation 1. Introduction Aluminium-Magnesium alloys have excellent corrosion resistance especially to seawater and industrially polluted atmospheres. EN AW 5754 finds use in almost every field of the industry due to its combination of many features such as very good welding ability, excellent corrosion resistance, superior cold forming, and very good anodizing ability. To endure critical conditions in aeronautic or marine applications some chemical processes, such as, conversion coatings, anodizing and chromatization are often applied as pre-treatment for Al alloys to improve corrosion resistance and enhance adhesion properties [1].

  • The Plasma Pretreatment of Plastics
    plasma electronic 6UCK i!!: TECHNOLOGIEN *I! *- 3 THE PLASMA PRETREATMENT . OF PLASTICS c . The plasma pretreatment of plastics 1. lntroduction A method of obtaining adherent compound structures which is more environment-friendly and operationally safe than conventional processes is the use of low-temperature plasmas. By contrast with conventional methods, these open up new possibilities for pretreatment as a means of promoting adhesion. - Grease, oil, wax and even silicons can be removed leaving no residues whatsoever. - Plastic surfaces can be roughened without harming the material or the use of aggressive chemical baths. - The wetting capability of homopolar plastics with adhesives, paints, printing inks, etc. can be radically improved. - Poorly defined surfaces can be given a very fine coating of primer. In the process, the workpieces undergoing treatment are exposed for a few seconds or mi- nutes to a "cold" plasma which is produced in a vacuum chamber by applying an electrical voltage to the respective process gas. The gaseous phase of the process is easy to monitor and control, and even workpieces of extremely complicated shapes can be treated. Since the reaction medium is heavily diluted, only relatively small quantities of chemicals are used, normally non-hazardous gases such as oxygen, argon, helium, ethylene or tetra- fluoromethane. Furthermore, since these are used in sealed chambers, no hazardous gases or fumes are produced at the workstation. By selecting the appropriate gas and adjusting the plant parameters accordingly, processes can be tailor-made to meet the specific application of the user. Some examples, taken hainly from the electrical and automotive industries, which describe the plasma process and its economical incorporation in the production sequence are given below.

This research was also performed in collaboration with TWI Ltd (Cambridge). ABSTRACT OF THE DISSERTATION Plasma Treatment for Adhesive Bonding of Aerospace Composite Components by Berta Navarro Rodríguez Master of Philosophy in Mechanical, Aerospace and Civil Engineering Brunel London University, 2016 Senior Lecturer Aerospace Engineering – Cristinel Mares Consultant Adhesive Technology TWI – Ewen Kellar Key words: composites, aerospace, cold atmospheric pressure plasma, adhesive bonding, surface pre-treatment A cold atmospheric pressure plasma source was investigated as an alternative pre-treatment for carbon fibre reinforced epoxy substrates prior to bonding. For reference, common surface pre-treatments were also investigated (peel ply, manual abrasion, and grit blasting). In the aerospace industry, the peel ply, is usually added to one side of the composite surface during manufacture and peeled off prior to bonding. Peel ply can be used independently or in combination with other techniques. The strength of the bonded joints of the different pre-treatments was assessed through tensile lap shear tests. It was found that combining peel ply with plasma increased the joint strength by 10% whereas manual abrasion or grit blasting after peel ply improved the strength of the joints by 15% and 20% respectively.
