Forming bacteria-repellent coating on polymer surfaces

摘要

A method for the preparation of a bio-active, covalently bonded coating on the surface of a substrate involves radiation-induced grafting of a coating polymer onto the optionally activated surface. The polymer is derived from acidic monomer(s) of formula (I) and monomer(s) (II) having a group sensitive to ultra-violet radiation. R-(A)a (I) R = mono- or di-olefinically unsaturated organic group (preferably hydrocarbyl) of valency a; A = COOH, OSO3H, SO3H, OP(O)(OH)2, P(O)(OH)2, OP(OH)2 or phenolic OH (all optionally in salt form); and a = 1-3.
