摘要

本工作用低压汞灯作为光源，以丙烯酸羟丙酯（2-Hydroxypropyl acrylate，HPA）为单体，对真丝绸的紫外光光化学接枝改性进行了系统研究，反应体系中无任何引发剂或者光敏剂。用衰减全反射红外光谱（Attenuated total reflectance infrared spectroscopy，ATR-IR）、差示扫描量热法（Differential scanning calorimetry，DSC）和热重分析（Thermal gravity analysis，TGA）等对光接枝产物进行了表征。探索了光照反应时间、单体浓度、pH值、多官能团单体的存在对接枝率的影响规律。研究表明，此方法可获得较高的接枝率，且低压汞灯具有无污染、设备简便价格低廉、寿命长，易于操作等优点，是一种有效的真丝绸改性方法。

Abstract

Silk fabric samples were grafted with 2-hydroxypropyl acrylate monomer by ultraviolet rays, and a light-initiated graft copolymerization system without any additives or co-additives had been established. Experiments were performed to study effects of monomer concentration, irradiation time, pH value on the grafting rate. FT-IR and DSC characterizations of the grafted silk samples were carried out to study the property changes in the silk fabrics. With advantages of fairly high graft rate, simpler equipment and operation and free of additives, the method may be an effective technique to improve the properties of silk fabrics.
