Thermal polymer composite materials for heat dissipation purposes have been widely researched over the previous decade due to their ease of processing, electric insulating, low cost and lightweight. These materials, which embedded with high thermal conductive fillers in the polymer matrix, exhibit high electrical insulation and thermal conductivity properties. These materials, however, are very hard to manage because usually it contains more than 70% volume of filler in order to be able to rapidly dissipate heat. Several approaches have been conducted by different research groups to enhance heat transfer through polymers while decreasing its filler contents. This paper presents a systematic review on several approaches which are used for enhancing the thermal properties of polymer composites by incorporating various types of fillers. The primary goal of this review is to identify any future trends in thermal polymer composites that regulate and dictate the method of thermal conduction.
