摘要

采用机械分散法制备了聚苯乙烯/高岭土复合薄膜材料。采用差示扫描量热法和热重法分析了复合材料的热破坏和弛豫转变。结果表明，用高岭土改性聚苯乙烯提高了玻璃化转变温度。发现复合材料的特征热破坏温度高于未改性聚合物的特征热破坏温度。采用Freeman-Carroll法确定了热分解的动力学参数。

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.

期刊介绍： Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
