ABSTRACT:
A procedure is described for wet chemical surface modification of formed articles and substrates coated with made of organopolysiloxanes: the articles formed were contacted with metal hydroxide solutions to tailor the binding capacity for ions, particularly metal ions, bivalent cations, organic macro anions, and organic macro cations, e.g. proteins. The procedure creates organopolysiloxane surfaces which are better wettable, have reduced surface resistance, are less sticky, are smoother and more biocompatible.
