Boron nitride/silicon dioxide composite film material as well as preparation method and application thereof
The invention discloses a boron nitride/silicon dioxide composite membrane material and a preparation method and application thereof, and belongs to the technical field of composite membrane material preparation. According to the boron nitride/silicon dioxide composite membrane material, boron nitride nanosheets serve as a matrix, silicon dioxide serves as a sintering binder, and the adding amount of silicon dioxide does not exceed 15 wt% of the total solid content of the composite membrane material. By adding silicon dioxide, a low-temperature molten state is formed in the sintering process, and the sinterability of a matrix and the mechanical property of the sintered composite film are enhanced. The silicon dioxide and the boron nitride nanosheet are sintered to form tight combination, so that the matrix shows multiple excellent properties. The invention provides a simpler process and process preparation method, the preparation time is shortened, and the preparation cost is reduced. In the prepared boron nitride/silicon dioxide composite film material, the silicon dioxide particles and the boron nitride nanosheets are sintered to form tight combination, so that the compression resistance, the dielectric property, the heat-conducting property and the thermal shock resistance of the material are improved.
