Adsorption of Ionic Surfactants to a Plasma Polymer Substrate

Atkin, R; Craig, Vincent; Hartley, Patrick G; Wanless, Erica J; Biggs, Simon


The adsorption of an anionic C12 surfactant and cationic C12 and C16 surfactants to a synthetic, anionic radio frequency glow discharge plasma polymer substrate has been investigated. This substrate has a similar charge density to that of amorphous silica but also possesses hydrophobic character, producing a water sessile contact angle of about 74° at pH values between 2 and 7. Both the cationic and anionic C12 surfactants had the same saturation surface excess values on the plasma polymer...[Show more]
