Spray-assisted assembled spherical boron nitride as fillers for polymers with enhanced thermally conductivity

Owing to its unique properties, such as electrical insulation, high thermal conductivity, high breakdown strength, physical and chemical stability, boron nitride has been used widely as fillers to improve the thermal conductivity of polymers. However, the addition of very small boron nitride leads to a dramatic increase of viscosity of polymer composites. The increased viscosity will limit the amount of boron nitride in polymers, which results...
