Poly(phenylene sulfide) (PPS)-based nanocomposite films containing pristine multiwalled carbon nanotube (MWCNT) of 1.0-10.0 wt% were manufactured by solid-state-mixing, hot-compression, and slow-cooling process. The microstructures, thermal and electrical properties of the nanocomposite films were investigated as a function of the MWCNT content. SEM images confirmed that MWCNTs were randomly dispersed in the PPS matrix. DSC and TGA data supported that the thermal transition temperatures as well as the degradation temperatures of the nanocomposite films were influenced by the MWCNT content and crystalline featured developed by slow-cooling. The electrical resistivity of the nanocomposite films were changed with increasing the MWCNT content by exhibiting a typical percolation threshold. Furthermore, the electric heating performance of the nanocomposite films with high MWCNT contents was systematically characterized in terms of temperature response rapidity at different applied voltages. |
