摘　　要：利用热重分析仪对PES-C/PSM复合材料的耐热性能进行分析,并以Kissinger法研究其热分解动力学,计算热分解表观活化能Ea。结果表明,在空气氛下复合材料的热分解温度随PSM含量的增大而升高,且当PSM的含量提高至1.0%,复合材料的热分解结束温度提高了41.29℃。复合材料的表观热降解活化能随PSM含量的增加而增大,与纯PES-C(Ea_(PES-C)=241 kJ/mol)相比,当PSM含量为1.0%时,PES-C/PSM复合材料的活化能为264.76 kJ/mol,较纯PES-C提高了9.86%。The heat-resistant property of PES-C/PSM composites were analyzed by thermogravimetric analyzer.The thermal decomposition kinetics of composites was studied by the method of Kissinger.The results showed that the thermal decomposition temperature of the composites in the air atmosphere increased with the increase of PSM content,and when the PSM content increased to 1.0%,the thermal decomposition ending temperature of the composite increased by 41.29℃.And the apparent thermal degradation activation energy(Ea)of composites increased with the increase of PSM content.The Ea of neat PES-C and PES-C/PSM was calculated and found to be 241.0 and 264.76 kJ/mol,respectively(increased by 9.86%).
