Moreover, the sulfamide groups on the SAMs can be hydrolyzed showing the partial regeneration of the aniline surface. SAMs were characterized by water contact angle (WCA) measurements, Fourier-transform infrared reflection absorption spectroscopy (IRRAS) and X-ray photoelec- tron spectroscopy (XPS). Introduction Self-assembled monolayers (SAMs) have raised considerable of reactive end groups in the monolayers enabling the chemical interest in the past decades because of their potential applica- functionalization of solid surfaces [3,5-7].
