摘要
以有机硅改性EP(环氧树脂)为聚合物基体、经强碱处理及硅烷偶联剂表面改性的MWCNTs(多壁碳纳米管)为功能性填料,采用原位聚合法制备了MWCNTs/有机硅改性EP复合材料。研究结果表明:经表面改性处理后的MWCNTs可在聚合物基体中良好分散,当w(MWCNTs)=0.6%(相对于有机硅改性EP质量而言)时,复合材料的拉伸强度(86.03 MPa)、弯曲强度(154.07 MPa)相对最大,并且比表面未改性的MWCNTs体系分别提高了17.12%、8.19%。
With organic silicon modified EP （epoxy resin） as polymer matrix, MWCNTs （multiwall carbon nanotubes） after strong alkali treatment and silane coupler surface modification as functional filler, a MWCNTs/ organic silicon modified EP composite was prepared by in-situ polymerization. The research results showed that the MWCNTs after surface modification treatment could be well dispersed in polymer matrix. The tensile strength （86.03 MPa） and bend strength （154.07 MPa） of composite with surface modified MWCNTs were relatively maximum, and were 17.12% and 8.19% respectively more than those of composite with surface unmodified MWCNTs when mass fraction of MWCNTs was 0.6% in organic silicone modified EP.
