| 中文摘要: |
| 研究端羟基聚丁二烯包覆多壁碳纳米管（MWNTs）的制备及其对顺丁橡胶（BR）的补强效果。结果表明：将MWNTs与HTPB研磨，可使聚合物包覆在MWNTs表面，显著提高MWNTs在甲苯等溶剂中的溶解性；对MWNTs进行羧酸化处理可进一步改善HTPB对MWNTs的包覆效果，提高MWNTs在BR中的分散性，增强MWNTs与BR的界面粘合力，使其在BR基体中表现出更好的补强效果。 |
| 英文摘要: |
| The multi-walled carbon nanotube（MWNTs） was modified by hydroxyl-terminated polybutadiene（HTPB） and its effect on the reinforcement of BR was studied.The results showed that the surface of MWNTs was wrapped by HTPB by grounding MWNTs with liquid HTPB，and then the solubility of MWNTs in solvents such as toluene was improved.When MWNTs was pretreated to have carboxylic groups functionalized on the surface，the modification efficiency of HTPB wrapping was increased，which resulted in better dispersion of MWNTs in BR，higher interfacial adhesion between MWNTs and BR，and improved reinforcement effect. |
