聚甲基丙烯酸甲酯/石墨烯导热复合材料的制备及性能研究OA北大核心CSTPCD
Research on Preparation and Properties of PMMA/GR Thermal Conductivity Composites
采用超声物理分散和原位聚合法制备了聚甲基丙烯酸甲酯/石墨烯(PMMA/GR)复合材料,运用金相显微镜对GR在甲基丙烯酸甲酯(MMA)单体中的分散状态进行了观察,并通过激光导热仪,热重分析(TG)、差热分析(DSC)、红外光谱(FTIR)对复合材料的导热性能,热稳定性,结构等进行了表征和分析.结果表明:延长超声时间可明显提升GR在MMA单体中的分散效果,有助于均质PMMA/GR复合材料的制备;GR的加入使PMMA的导热系数显著提高,低填充时的最佳填…查看全部>>
The polymethyl methacrylate/graphene (PMMA/GR) composites were obtained by ultrasonic physical dispersion and in-situ polymerization.Metallographic microscope was used to characterize the dispersion of GR in methyl methacrylate (MMA) monomers.And then the thermal conductivity,thermal stability and structures of the PMMA/GR composites were investigated by means of thermal conductivity tester,TG,DSC and FTIR.The results indicate that the prolonging of ultrason…查看全部>>
