| 摘 要： | 将溶液浇铸法制得的聚乙烯醇(PVA)薄膜用不同温度的硼酸饱和溶液进行不同时间的改性处理,对改性后薄膜的耐热性和耐水性进行了研究。结果表明:经过硼酸溶液改性处理后,PVA薄膜的热变形温度Tg小幅度上升,Tm呈下降趋势;从吸湿率的变化来看,改性处理后,薄膜的耐水性得到明显提高。

| Abstract: | The poly（vinyl alcohol） film was prepared by casting the aqueous solution containing 10%wt PVA,subsequently was immersed into boric acid solution with a variety of concentration and the dipping time was also controlled.The thermal performance and water resistance of the modified film were investigated.The result indicated： after modification,the glass transition temperature（Tg） of the film increased but melting point decreased.The water resistance of the film was strengthened obviously. |
