Received: 11 August 2020; Accepted: 16 September 2020; Published: 23 September 2020 Abstract: The present study explores the exploitation of ladder-like polysilsesquioxanes (PSQs) bearing reactive functional groups in conjunction with SiO2 nanoparticles (NPs) to produce UV-curable nanocomposite coatings with increased hydrophobicity and good thermal resistance.
