Abstract:

Polycarbonate (PC) membranes with regular and vertical channels were prepared by electron beam (EB) with the methods of masks and oxygenation corrosion. Ubbelohde viscometer, gel permeation chromatography (GPC), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR) were used to characterize the structure and properties of irradiated PC. The results showed that the relative molecular weight, number average molecular weight and glass transition temperature of PC decreased with the increasing absorbed doses. Infrared analysis showed that the main chain of PC ruptured after being etched by electron beam. The kinetic analysis showed that the irradiation degradation of PC was a type of non-conventional degradation, giving the theoretical basis for the preparation of PC microporous membrane by electron beam etching.
