Title Mixed polymer brushes on polyamide substrates

Abstract Mixed polymer brushes were shown to form responsive coatings which switch their morphology driven by interplay between lateral and vertical phase segregation upon exposure to selective solvent. We develop the route to fabricate the mixed brushes on polyamide substrates by "grafting from" approach. PA substrates were functionalized by NH3-plasma and the azo-initiator of radical polymerization was covalently bond to the PA surface. Two-step grafting procedure was applied to graft polystyrene and poly(2-vinylpyridine) to fabricate the mixed brush on the PA surface. The synthesized brushes reveal pronounced responsive properties. Additionally, we performed the same grafting procedure on the surface of PA fabric. In this case the switching behavior was amplified by a composite morphology of the material: wettability of the textile with the mixed brush was switched from complete wetting to highly hydrophobic state (130o water contact angle).<br /><br />Polymer Surfaces and Interfaces<br />The 225th ACS National Meeting, New Orleans, LA, March 23-27, 2003
