Abstract
The mechanism by which surface modification of two kinds of synthetic rubbers (ethylene-propylene and chloroprene) was brought about by ultr aviolet (UV) irradiation and sputter ion etching treatments was studie d from a physicochemical point of view. The most remarkable effect of this irradiation treatment was the rapid increase in adhesion properti es and the simultaneous decrease in self-stickiness. This nonsticking effect was particularly important for the rapid production of articles from thin rubber sheets. The surface modification mechanism was studi ed by use of SEM, ESCA, FTIR, and related interfacial analytical proce dures. It was shown that surface roughening with a quite thin layer of surface oxidation (similar to 0.5 mu m in depth) is a key factor for the development of nonsticking properties.
