摘　　要：用自制的三元共聚物BA-MMA-GMA作为大分子处理剂,对多壁碳纳米管(MWNTs)进行表面改性。结果表明:改性后的MWNTs有良好的分散性能。当MWNTs加入质量分数为0.2%～0.3%时,MWNTs/合成革用聚氨酯树脂纳米复合材料其综合性能较好,主要表现在拉伸强度、断裂伸长率和最大力3项性能上。当MWNTs加入质量分数在0.05%～0.15%时,纳米复合材料的耐水解性能优异。The method using self - regulated BA - MMA - GMA as surface coating treatment agent for MWNTs was intro- duced. The results show that the modified MWNTs has better dispersivity. MWNTs/PU nano -compound shows following excellent properties, tensile strength and elongation at break, etc, when modified MWNTs are added to PU with the mass fraction of 0. 2% - 0.3%. While the mass fraction of MWNTs add at 0.05 % -0.15 %, the nano -composit exhibit good hydrolysis resistance against water property.
