Role of Filler-Polymer Interface on the Thermal Conductivity in Polymer Composites
Abstract: Polymers with high thermal conductivity are the need of modern technologies due to their robustness, cost-effective, and less corrosiveness. However, bare polymers are not good heat-conductors due to their molecular structures, and their non-metallic properties. Therefore, metallic fillers of different shape and size have been used to enhance the thermal conductivity in polymer-composites. However, there has been search of best geometrical fillers which can maximize the thermal conductivity effectively with …
