Abstract
In this work, dynamic mechanical properties and viscosity of multiwalled carbon nanotubes reinforced poly (phenylene sulfide) nanostructured composites obtained by melt mixing techinique were investigated. The storage modulus (E') and the glass transition temperature (Tg) showed increases up to 130% and 11 °C for concentrations of 2.0 wt% compared to neat PPS. In Addition, it was observed for concentrations above 1.0 wt% an increment of complex viscosity (η∗), suggesting the formation of an interconnected nanotube structure within the polymeric matrix.
