摘要
蓄热调温纺织品是一种新型的智能纺织品,大多采用相变材料(PCM),要求PCM稳定性好、安全、无毒副作用,并有较好的可后整理性能。采用新型微胶囊成形方法,利用核壳聚合原理,制备出直径≤2μm、包覆容量为46%的相变储能微胶囊,并用扫描电镜(SEM)和热分析(DSC)对微胶囊形状及热性能进行表征,为解决智能纺织品用相变材料及其实用化提供了新途径。
Microcpsules are prepared by the method of core-shell polymerization with acrylonitrile as the outer membrane and a phase change materials as core. The surface morphology, diameter, melting point of the microcapsules are investigated by using SEM, DSC. Thought optical microscope double focusing method, we got the membrane thickness of the microcapsule. The experiment showed that the optimized parameters for microcapsule production were discussed and presented as： shell：core -1：2, under the environment of 60℃ and 8000 r/min for 1h. The shell thickness of microcapsule wsa obvious effect by speeds of emulsification and less effect by the increaing the content of the core. The investigation by DSC showed the melt point of phase change materials in shell was not change and the heat transmit was obvious.
