Effects of Al2O3 on Thermal Conductivity of Silicone Rubber

Article Preview

Abstract:

Thermal conductivities of silicone rubber filled with Al2O3 were prepared. Thermal conductivity experimental results obtained were analyzed using the Nielsen and Agari models to explain the effect of Al2O3 filler on the formation of thermal conductive networks. Thermal conductivities increased with the adding of mixed Al2O3 of large and small sizes fillers. The scanning electron microscopy (SEM) showed that it is the optimum particle sizes and quantities that made the filler packing closer, which thus leads to formation of more thermal conductive chains.
