| Abstract: | Nano-silver coated Al2O3 particles were prepared by chemical method, and the silver nanoparticles kept stable in air. This coating layer enhanced the thermal conductivity of Al2O3/silicone rubber (SR) composites. The microscopic topography of the composites showed that the coating layer improved the interface bonding between Al2O3 and silicone rubber, and the silver particles bridged the adjacent Al2O3 particles. |
