阅读说明:本技术 一种超快生长石墨烯的方法 (Method for ultra-fast growth of graphene ) 是由 徐建勋 赵宇亮 梁建波 葛逸飞 王鲁峰 杨宜 于 2020-04-24 设计创作,主要内容包括:本发明提供一类在金属、非金属平面以及针尖基底表面大面积超快生长石墨烯的方法,所述金属基底优选为Fe、Ni、W等,非金属基底优选为玻璃、硅、氮化硅、高分子材料等。本发明针对不同材料的性质,利用脉冲电流、感应电流或汇聚微波能等作用于碳化后的基底材料,通过基底表面的电流原位产生大量的热,实现材料的瞬间淬火进而在材料表面生成大范围的连续单层或多层石墨烯。本发明所述方法,可在不耐受长时间高温的材料表面生长界面接触良好的石墨烯;本发明提供的方法可不受真空管式炉的尺寸限制,实现大尺寸基底材料上的石墨烯生长。本发明提供的石墨烯生长方法具有材料和环境适应范围广、快速、能耗低等特点。(The invention provides a method for ultra-fast growing graphene on a large area on the surfaces of a metal plane, a nonmetal plane and a needle point substrate, wherein the metal substrate is preferably Fe, Ni, W and the like, and the nonmetal substrate is preferably glass, silicon nitride, a high polymer material and the like. According to the invention, aiming at the properties of different materials, pulse current, induction current or converged microwave energy and the like are utilized to act on the carbonized substrate material, and a large amount of heat is generated in situ through the current on the surface of the substrate, so that the instant quenching of the material is realized, and continuous single-layer or multi-layer graphene in a large range is generated on the surface of the material. According to the method, good graphene can be contacted with the growth interface on the surface of the material which does not resist high temperature for a long time; the method provided by the invention is not limited by the size of the vacuum tube furnace, and the growth of graphene on a large-size substrate material is realized. The graphene growth method provided by the invention has the characteristics of wide material and environment application range, rapidness, low energy consumption and the like.)
