摘要:

采用共混体系制备壳聚糖(CS)水凝胶、聚乙烯醇水凝胶、透明质酸水凝胶、聚丙烯酰胺水凝胶,对比史莱姆水凝胶、去离子水,探究不同水凝胶在隔热保温方向的热管理性能,筛选在两侧温差不大的场景下,具有优异热管理性能的水凝胶材料。结果表明,CS水凝胶的隔热性能、热锁水性能最优异,且具有阻燃性能,在两侧温差不大的场景下,可作为热管理材料使用,并研究分析了CS水凝胶的隔热机理。

Abstract:

CS (chitosan)⁃, polyvinyl alcohol⁃, hyaluronic acid⁃, polyacrylamide⁃based hydrogels were prepared by using a blending method. Through comparing these hydrogels with the Slime hydrogel and deionized water, the thermal management performance of different hydrogels in the direction of heat insulation and heat preservation was investigated, and the hydrogel materials with excellent thermal management performance were selected in the scenarios at the temperatures with a less difference between the two sides. The results indicated that the CS⁃based hydrogel had the most excellent thermal insulation, thermal water locking, and flame⁃retardant performance. It could be used as a thermal management material in the scenarios at the temperatures with a less difference between the two sides. The thermal insulation mechanism of the CS⁃based hydrogel was also analyzed.

Key words: chitosan hydrogel, thermal insulation, thermal management material
