摘要

聚乙烯醇膜于水溶胀状态经电子束辐照交联得到透明的水凝胶膜，这种材料强度较低，弱而易碎。将辐射交联水凝胶膜室温脱水，于90～160℃范围内，不同温度下恒温热处理1～2小时。DSC和X-衍射测定表明，热处理后的水凝胶膜的结晶度从25%上升至43%。力学性能测定表明，其模量和断裂强度由于水凝胶的部份结晶化而得到提高。

Abstract

The water-swollen films of poly(vinyl alcohol) were crosslinked via electron-beam irradiation to form transparent hydrogel films, The material we obtained was weak and easily shattered. After slow dehydrating at room temperature then heating at 120~160℃ for 1~2 hours, it was reinforced due to induction of partial crystallization. The degree of crystallinity varies from 25% to 43%. The measurement of the mechanical properties of the crystallized hydrogel films showed that modulus and ultimate strength were improved.
