Thermal Behaviors of Polystyrene/Halloysite Film Composites

Polystyrene/halloysite composite film materials were prepared by the mechanical dispersion method. Differential scanning calorimetry and thermogravimetric analysis were used to examine thermal destruction and relaxation transitions in the prepared composites. It was established that modification of polystyrene with halloysite raised the glass-transition temperature. The characteristic thermal destruction temperatures of the composite were found to exceed those of the unmodified polymer. The kinetic parameters of the thermal decomposition were determined using the Freeman–Carroll method.
