摘　　要：采用溶液共混及原位复合法制备多壁碳纳米管/杂萘联苯聚醚砜酮复合材料。通过扫描电镜观察材料的形貌,并对材料性能进行研究。对比两种方法,结果表明通过原位复合法制备,碳管在基体中有较好的分散和界面结合,其力学性能和导电性优于溶液共混法制备的复合材料。当碳管含量为3%(质量分数)时,原位复合材料的拉伸模量和强度分别为2.4GPa和107.6MPa,其体积电阻率达到1.0×106Ω·cm,5%热失重温度提高了20℃。Multiwalled carbon nanotubes/poly（phthalazinone ether sulfone ketone） s composites have been prepared by in situ polymerization and solution mixing method. The morphology and structure of composites were characterized by scanning electron microscopy and the properties have been investigated. Comparatively, MWNT/PPESK composites prepared by in situ polymerization have more sufficient dispersion and better properties than the solution mixing composites with the same MWNT content. The tensile strength and the Young＇s modulus are 107.6MPa and 2.4GPa for the composite with 3wt% MWNT,respectively. And the volume resistivity reaches 10^6Ω ·cm,5% weight loss is improved by about 20℃ from 484-504℃.
