Abstract
Polycarbonate(PC) has lightweight, ductility, low cost, high productivity and high heat resistance, which are utilized for biomedical and electrical articles, as well as wear, automobile and architecture. However, PC usually occur Hydrolysis at High temperature and high humidity environment. Thus it is a serious problem to use PC in automobile. On the other hands, our laboratory reported influence of mechanical property of polymer materials by homogeneous low energy electron beam irradiation (HLEBI). HLEBI If HLEBI probably cuts off the weakest C-O bonds at esteratic sites, HLEBI induced suppression of hydrolysis of PC can be expected. Therefore, the apparent influences of HLEBI on the water absorption and hydrolysis reaction of PC dipped in boiling water have been precisely investigated as a basic research.
