A triethoxyacetylenic silane (TEOAS) was synthesized to treat the surface of hydroxylated multiwalled carbon nanotubes (MWCNTs), and then the MWCNTs-T was obtained and characterized. PSA/MWCNTs and PSA/MWCNTs-T composite resins were prepared using solution method by mixing silicon-containing polyarylacetylene (PSA) with MWCNTs and MWCNTs-T, respectively. The thermal conductivity, thermal stability, electric insulation, and bending properties of the PSA/MWCNTs and PSA/MWCNTs-T composites were investigated. The results show that TEOAS was grafted on the surface of MWCNTs successfully, and MWCNTs-T is compatible with PSA matrix. The thermal conductivity of the composites increases with the increase of the mass fraction of MWCNTs and MWCNTs-T. The effect of MWCNTs-T is more obvious, with the mass fraction of 2%, the thermal conductivity of PSA/MWCNTs-T reaches 0.62 W/(m·K), which is 3 times as higher as that of PSA. The introduction of MWCNTs and MWCNTs-T can decrease the thermal stability and bending properties of PSA, the effect of MWCNTs-T is smaller than that of MWCNTs. The glass transition temperature of the PSA/MWCNTs is higher than 500℃, the electrical resistivity of the composite resin decreases linearly with the increase of frequency, while is still higher than 108 Ω·cm at 106 Hz.
