| Abstract: |
| The effect of the addition level of modified carbon nanotubes（CNTs） and mixed CNTs on the properties of polymethyl-vinyl siloxane rubber（MVQ）was investigated.The results showed that，with the increase of the addition level of modified CNTs，the curing degree of the compound increased, t90 was extended, the Shore A hardness，modulus at 100% elongation，tear strength，thermal diffusion coefficient and thermal conductivity of the vulcanizates increased，the tensile strength and DIN abrasion loss changed little，the elongation at break was decreased, and the surface resistivity and volume resistivity decreased only slightly.Similar change of properties was found for the mixed CNTs filled MVQ，and the physical properties，electrical conductivity and thermal conductivity of mixed CNTs reinforced MVQ was better. |
