Hexagonal boron nitride thermal conductivity enhancing materials and method of making

摘要

A porous hexagonal boron nitride (h-BN) material with thermally conductive properties, includes a network of interconnected struts and nodes. The porous h-BN material is formed by depositing h-BN onto a catalyst foam using chemical vapor deposition at atmospheric pressure. The catalyst foam with the h-BN layer deposited thereon is then encapsulated with an insulating material. After the insulating material layer is cured, the h-BN structure is cut on an edge and then wet-etched to at least partially remove the catalyst foam.
