制备了多壁碳纳米管/氰酸酯/环氧树脂（MWCNT/CE/EP）纳米复合材料。为了提高多壁碳纳米管在聚合物基体中的分散性能，采用等离子体聚合法对多壁碳纳米管进行了功能化处理。研究了MWCNTs的质量含量和功能化对复合材料室温和液氮温度（77 K）下力学性能的影响。结果表明，等离子体功能化处理提高了MWCNTs的分散性能和与基体的界面结合。官能化的MWCNT/CE/EP纳米复合材料显示出更大的改善比收到MWCNT/CE/EP纳米复合材料的机械性能。的拉伸强度，拉伸模量，并在室温和77 K的冲击强度同时增强与功能化的MWCNTs的加入。纳米复合材料在77 K下的拉伸强度和模量远高于RT。（C）2013 Elsevier Ltd.保留所有权利。
Multi-wall carbon nanotubes/cyanate ester/epoxy (MWCNT/CE/EP) nanocomposites were prepared. The MWCNTs were functionalized by a plasma polymerization process in order to improve the dispersion property of MWCNTs in the polymer matrix. The effect of mass content and functionalization of the MWCNTs on the mechanical properties at room temperature (RT) and liquid nitrogen temperature (77 K) of nanocomposites were investigated. Results showed that the plasma functionalization of MWCNTs improves the dispersion property and interfacial bonding between MWCNTs and matrix. The functionalized MWCNT/CE/EP nanocomposites showed much greater improvement on mechanical properties than as-received MWCNT/CE/EP nanocomposites. The tensile strength, the tensile modulus, and the impact strength at RT and 77 K were simultaneously enhanced with the addition of functionalized MWCNTs. The tensile strength and modulus of the nanocomposites at 77 K were much higher than those at RT. (C) 2013 Elsevier Ltd. All rights reserved.
