Decomposition kinetic study of nanostructured composites of poly (phenylene sulfide) reinforced with carbon nanotubes

The aim of this work is to obtain nanostructured composites of poly (phenylene sulfide), PPS, reinforced with multiwalled carbon nanotubes, MWCNT, by melt mixing technique and further characterization of their morphological and thermal properties. Transmission Electron Microscopy analysis was carried out to evaluate the quality of MWCNT dispersion throughout the PPS matrix. Thermogravimetry shows an increase in the maximum degradation temperature by the addition of the nanofiller to the polymeric matrix. In addition, Ozawa-Wall-Flynn modeling was used to determine the degradation parameters. The results showed that the maximum degradation temperature increased by ca. 25 ºC when a very small concentration of MWCNT (0.5 wt %) was considered, contributing to improve the thermal stability of PPS.
