摘　　要：采用反复冷冻-解冻的方法制备了聚乙烯醇/丝胶共混凝胶薄膜,考察了薄膜热性能、力学性能和在水中的失重率,并对其微观结构进行了分析。结果表明:当制备过程中循环冷冻-解冻次数增加,且共混薄膜中丝胶与聚乙烯醇的含量相等时,可提高薄膜的综合性能。The hydrogel membranes of PVA/Sericin thermal properties, solubility in water and mechanical proposed, the micro structure of the membranes was content of sericin and PVA keep constant, properties were prepared by freeze/thaw cycles. The properties of the hydrogel membranes were characterized. Results show that when the can be enhanced with the increasing of the numbers of freeze/thaw cycles.
