摘　　要：采用原位聚合法制备了以石蜡(PA)为芯材、三聚氰胺-甲醛-树脂为壁材、碳纳米管(CNT)及纳米铜(CNP)为导热粒子的改性相变微胶囊。结果表明:随着CNT和CNP添加量的增加,CNT改性相变微胶囊(MPCM/CNTs)的导热系数从0.25W/(m·K)增大到0.38W/(m·K),最大增加率为52%;CNP改性相变微胶囊(MPCM/CNPs)导热系数从0.25W/(m·K)增大到0.47W/(m·K),最大增加率为88%。In this paper,modified phase change microcapsules(MPCMs)were prepared by in-situ polymerization with paraffin as core material,melamine-formaldehyde-resin as wall material,and carbon nanotubes(CNT)and nano-copper(CNP)as thermal conductive particles.The results showed that the thermal conductivity of CNT-modified MPCM(MPCM/CNTs)increased from 0.25W/(m·K)to 0.38W/(m·K)with the increase of CNT and CNP,and the maximum increase rate was 52%.The thermal conductivity of MPCM/CNPs increased from 0.25W/(m·K)to 0.47W/(m·K),with a maximum increase rate of 88%.
