Multi-walled carbon nanotubes (MWNT) have been shown to improve the thermal properties of plastics such as polypropylene (PP) at low heating rates (10 K/min or less). Military applications have also examined thermal degradation kinetics for PP-MWNT at heating rates similar to a ballistic event through laser pulse heating. This study examined the kinetics at heating rates ranging from 30 K/min to 195 K/min in order to bridge a gap between the low heating rates and the laser pulse heating experiments. The degradation experiments were completed with a Thermogravimetric Analyzer. The rate constants and activation energies were determined through the use of kinetic software. The results show that the MWNT increase the thermal stability of the polymer, as measured by the increased decomposition temperature. The results of the study are compared to the traditional lower heating rates and laser pulse heating experiments.
