| Abstract: |
| 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. |
