EBI Joining Between Different Polymers Without Adhesive Materials

摘要

Joining between Nylon-film and Silicone-rubber was successfully developed by using homogeneous electron beam (EB) irradiation. Effects of EB irradiation on joining strength of different polymers without adhesive materials were investigated. Although excess EB-irradiation more than 0.3MGy apparently decreased the joining strength, the EB irradiation increased the joining strength of the joining sample between Nylon-film and Silicone-rubber. To discuss the influences of EB irradiation on the joining strength, electron spin resonance (ESR) signals related to dangling bonds were observed. Since EB irradiation generated dangling bonds on Nylon-film, dangling bonds probably supported the different polymers at interface.
