蓄热调温纤维用DA@PMMA相变微胶囊的制备及表征OA北大核心CSTPCD
Preparation and characterization of n-dodecyl alcohol/polymethyl methacrylate phase change microencapsules used in thermo-regulating fibre
基于正十二醇(DA)相变温度(约22℃)处于人体最佳舒适温度18~28℃范围内,采用DA为相变芯材,聚甲基丙烯酸甲酯(PMMA)为包封壁材,通过原位聚合法制备蓄热调温纺织品纤维用DA@PMMA相变微胶囊,并对相变微胶囊的形貌、粒径分布、热性能及抗压性进行表征.结果表明:DA@PMMA相变微胶囊粒径分布集中于1.232μm附近;壁材表面光滑致密;相变温度为18.7~25℃,热焓值为92.3 J/g,芯材包封率为84.7%,且具有较好的抗压性;可用于制备蓄热调温纺织品纤维.
Due to the phase change temperature (about 22 ℃) of n- dodecyl alcohol (DA) was in the com?fortable temperature range (18~28 ℃) of human body, it was selected as the core material, and polymethyl?methacrylate (PMMA) as wall material, DA@PMMA phase change microcapsules was prepared by in- situ po?lymerization method. The morphologies, particle size distribution, chemical composition, thermal and compres?sive properties of resulted microcapsules was characteri…查看全部>>
