相变调温羊毛蛋白膜的制备及其热性能表征

Preparation and thermal properties characterization of phase change wool protein membrane

采用界面聚合的方法,通过乳化的方式直接把含有反应物质的石蜡混合液混入到羊毛蛋白改性腈纶混合液中,使含有反应物质的石蜡形成相变微胶囊,制备出了相变调温羊毛蛋白膜。通过对微胶囊的形态以及羊毛蛋白膜的热性能分析发现:采用界面聚合法制备的微胶囊结构完整,微胶囊与羊毛蛋白纺丝液相容性较好,用其制备的羊毛蛋白膜具有一定的调温功能;以硫氰酸钠为溶液制备的羊毛蛋白膜的热性能优于以氯化锌溶液制备的羊毛蛋白膜。

Interfacial polymerization method was adopted to mix paraffin liquid containing reaction material with wool protein modified acrylic mixture by emulsion method, and wool protein membrane with microcapsule were developed, which can adjust temperature by phase change. Surface morphology of microcapsules and thermal property of wool protein membranes were analyzed, it was found that the structure of microcapsule was complete, and the compatibility with wool protein spinning solution was good, the wool protein membranes prepared by the microcapsules and protein spinning had temperature regulating function. The thermal performance of the wool protein film prepared with sodium-thiocyanate solution was better than that prepared with zinc chloride solution.
