“…Plastic materials find extensive applications across various industrial sectors and the consumer goods industry [2][3][4]. Notably, one of the most significant areas where plastics have made a remarkable impact is in serving as materials for electrical devices [5][6][7]. However, many polymeric materials exhibit thermal insulating properties, with thermal conductivity typically ranging from 0.1 to 0.5 W/m•K.…”

In the present work, AlN was modified with vinyltriethoxysilane (VTES), and its effect on the properties of a thermally conductive composite of high impact polystyrene (HIPS), and AlN was investigated. Three composites, HIPS/AlN5, HIPS/AlN9, and HIPS/moAlN9, were prepared by mixing HIPS and AlN in a toluene solution, followed by hot pressing. The HIPS/AlN composite was characterized by tensile test, impact strength, flexural strength, and hardness shore D. The sample HIPS/moAlN9 showed the improvement of these properties compared to that of the HIPS/AlN9 sample. The increment of those mechanical properties was due to the good interaction between the modified AlN and HIPS resin matrix, which was revealed by morphology observation by SEM. Incorporating modified AlN into the HIPS matrix was also found to enhance the thermal conductivity by about 20%, from 0.15 for HIPS to 0.18 (W/m·K) for HIPS/moAlN9. It was explained due to the good adherence of AlN to the HIPS, which provided more thermal conductive routes than HIPS/AlN. This approach provides a possible strategy to prepare thermally conductive HIPS composite, which may be suitable for electronic device that required heat dissipation.
