| 摘 要： | 采用共价接枝法制备了羧基化碳纳米管(MWCNTs -COOH)、二氨基二苯基甲烷修饰碳纳米管( MWCNTs -DDM)、硼酸化碳纳米管(MWCNTs- Borate)修饰碳纳米管(MWCNTs).通过原位聚合的方法制备了修饰碳纳米管/硼酚醛树脂.使用3种碳纳米管改性的树脂制备了摩擦材料并研究了其摩擦性能.结果表明,修饰碳纳米管的加入,有助于提高摩擦材料摩擦系数的稳定性,减小磨损率,改善热衰退性.其中添加质量分数为1％的MWCNTs- Borate的情况改善最大,磨损率减小43.2％,摩擦系数和磨损率衰退率仅为10.3％和28.6％,摩擦表面保持完好.

| Abstract: | Three kinds of carbon nanotubes,carboxylated carbon nanotubes(MWCNTs-COOH),diamino biphenyl methane modified carbon nanotubes(MWCNTs-DDM) and boric acid modified carbon nanotubes(MWCNTs-Borate),are prepared by covalent grafting method.The modified MWCNTs with phenolic resin(BPR) are composed by in-situ polymerization.These modified carbon nanotubes(m-MWCNTs) are added into the phenolic resin-based friction materials.The results show that the stability of the friction coefficient of friction material is impr... |
