日前,中航工业北京航空材料研究院成功突破制备大尺寸、高质量石墨烯薄膜的技术难题,掌握了衬底材料表面晶粒定向受控生长和化学气相沉积(CVD)反应气体分压配比等关键专利技术,在铜箔表面制备出超过12英寸的石墨烯薄膜,更大尺寸的石墨烯薄膜制备技术也已突破,近期将批量生产。据悉,中航工业航材院投资数千万元,通过集智攻关,实现了大尺寸、高质量
Recently, AVIC Beijing Institute of Aeronautical Materials successfully broke through the technical difficulty of preparing large-sized and high-quality graphene films, grasped the controlled growth of grain orientation on the surface of substrate materials and the partial pressure ratio of chemical vapor deposition (CVD) reaction gases Key patented technology, in the copper foil surface prepared more than 12 inches of graphene film, larger size graphene film preparation technology has also been a breakthrough, the recent mass production. It is reported that AVIC Aviation Materials Institute invested tens of millions of dollars, through the wisdom research, to achieve a large size, high quality
