ABSTRACT:

The multi-walled carbon nanotubes were directly compounded with poly(phenylene sulfide) (PPS) via melt mixing. The morphology and physical properties, including viscoelasticity, electrical conductivity, thermal and mechanical properties of the obtained composites were investigated. The results show that the purified nanotubes can be fully dispersed in the PPS matrix especially at low loading levels due to their nice affinity. The composites hence present relative low rheological and electrical percolation threshold. The presence of nanotubes, on the one hand, show good reinforcement effect due to the strong interfacial interactions with the PPS matrix, which is confirmed by the strain overshoot flow behavior; on the other hand, act as a nucleation agent, promoting crystallization of the PPS matrix. Both contribute to evident improvement of tensile strength and dynamic mechanical properties of the composites.
