Recycled Natural Rubber-Based Composites Reinforced with Nano Boron Nitride in Thermal Conductive and Electrical-Insulating Fields

Abstract

In this research, recycled natural rubber (NR) based composites reinforced with the doped nano boron nitride (NBN) with the high resolution in thermal conductive and electrical-insulating field were designed, and their properties were studied. Good distribution of doped NBN in the matrix has shown substantial increments of thermal conductivity and high electrical insulation depending on the quantity in the matrix. Additionally, the thermal analysis indicates that NR/NBN composites have excellent heat-transfer capacity during heating and cooling processes, which suggests great potential application in thermal conductive and electrical insulating fields. The procedure can find multiscale particle-matching ways to achieve the maximum effective thermal conductivity under a given filler load. It should be emphasized that the optimized effective thermal conductivity obviously can be improved with the increase in the volume fraction of the reinforcement. © 2023, The Society for Experimental Mechanics, Inc.
