摘要

以电子束刻蚀技术和聚碳酸酯(Polycarbonate, PC)材料本身的辐照裂解特性,结合微孔掩膜和溶液氧化腐蚀的方法,成功制备了具有规则垂直孔道的PC微孔分离膜。用乌氏粘度计、凝胶渗透色谱仪、仪和傅里叶红外光谱分析仪表征辐照PC的结构和性能变化。结果表明,PC材料的黏均相对分子量、数均分子质量、玻璃化温度、黏均聚合度均随吸收剂量的增加而下降;红外分析表明PC在电子束照射下发生主链断裂;动力学分析表明其辐照降解属于无规降解类型,为电子束刻蚀制备PC微孔分离膜技术提供了理论依据。

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.
