The thermal percolation model is one of several models for analyzing the thermal conductivity behavior of polymer composites, in especial, and is known to be able to explain the rapid improvement in the thermal conductivity due to the contact between fillers by increasing the filler content in the composites. However, it is difficult to accurately interpret the thermal conductivity behavior of polymer composites with a segregate structure, which is one of the structural control strategies for improving the thermal conductivity of composite materials, using the thermal percolation model. In this study, an epoxy composite with a segregate structure using hexagonal boron nitride fillers and pelletized epoxy was prepared, and the thermal conductivity behavior was analyzed with a modified thermal percolation model including excluded volume effect.
