Abstract

By using homogeneous electron-beam (EB) irradiation, rapid adhesion between nylon-6 film and polymethyl methacrylate (PMMA) was successfully developed. Effects of homogeneous irradiation of electron beam with low potential (HIEBL) on adhesive strength of different polymers without glue were investigated. HIEBL less than 0.216MJ kg-1 (MGy) increased the adhesive strength and its strain of composites constructed with nylon-6 film and PMMA, although additional HIEBL at more than 0.432 MGy apparently decreased the adhesive strain. HIEBL less than 0.432 MGy also enhanced the elasticity (ds/de)o of composites. To evaluate the influence of HIEBL on the adhesive strength, electron spin resonance signals that relate to dangling bonds were observed. Because EB irradiation generated dangling bonds in polymethyl methacrylate and nylon-6, dangling bonds probably acted reactive and bonding sites to each polymer at interface. Therefore, HIEBL enhanced the adhesive strength as well as elasticity of the composites.
