CATALYTIC SYNTHESIS METHOD OF HIGH QUALITY HEXAGONAL BORON NITRIDE FROM BORAZINE OLIGOMER PRECURSORS AND HIGH QUALITY HEXAGONAL BORON NITRIDE OF THE SAME

摘要

The present invention relates to a high quality boron nitride film grown by a metallic catalyst effect by using borazine polymers as precursors which enables high quality high crystalline hexagonal boron nitride film to be easily synthesized by manufacturing a boron nitride precursor solution by melting borazine polymers in a solvent and performing annealing after coating an upper layer or a lower layer of a metallic catalyst layer with the same, and to a manufacturing method thereof. The present invention is capable of conveniently synthesizing a high quality hexagonal boron nitride film at low costs by solving problems such as gas precursor control, vapor pressure control and the like which are the problems of an existing CVD method, is capable of coating various structures and materials with the hexagonal boron nitride film, is capable of selectively coating a desired area and is conveniently applied to the coating of composite materials and various materials by being easily large-scaled.
