采用分散聚合法,二乙烯苯为交联剂,制备了石蜡/P(MMA-co-MAA)相变储能微胶囊。采用光学显微镜,扫描电子显微镜(SEM)、差示扫描量热仪(DSC)和热重分析仪(TGA)对其进行表征。实验结果表明:微胶囊呈球形,平均粒径为4.2 um,几乎没有粘结,其相变温度为27.24℃,相变潜热为81.53 J/g,芯材含量达到72.6%,同时具有良好的热稳定性。

By using dispersion polymerization, methyl methacrylate/methacrylic acid co-polymer as shell with divinylbenzene （DVB） as a cross-linking agent. microcapsules containing phase change paraffin were synthesized. The microencapsutated phase change materials （microPCMs） was charaterized by optical microscope, scanning electron microscope, differential scanning calorimetry （DSC） and thermogravimetry analysis （TGA）. The experiment results show that： The microcapsulate shape is spheric, the average particle size is 4.2 urn, no coagulation of ...
