阅读说明：本技术 垂直支化石墨烯 (Vertically branched graphene ) 是由 Z·韩 C·楚尼斯 R·阿玛尔 于 2020-02-28 设计创作，主要内容包括：提供了制备垂直支化石墨烯的方法,其包括在缺乏引入的碳源的情况下用惰性等离子体处理原始垂直石墨烯,以产生垂直支化石墨烯。该方法还以可包括用惰性等离子体预处理基底表面；通过使基底表面与包含碳源气体的沉积等离子体接触一段沉积时段,将原始垂直石墨烯沉积到基底表面上。还提供了附着于基底表面的垂直支化石墨烯,该垂直支化石墨烯具有从基底表面延伸的主体部分,所述主体具有随着与基底表面的距离增加而增加的支化度；和具有近端和远端的独立式支化石墨烯,近端包括主体部分,主体部分具有支化度,并且该支化度随着与近端的距离增加和与远端的距离减少而增加。(Methods of preparing vertically branched graphene are provided, which include treating pristine vertical graphene with an inert plasma in the absence of an introduced carbon source to produce vertically branched graphene. The method may further comprise pretreating the substrate surface with an inert plasma; pristine vertical graphene is deposited onto a substrate surface by contacting the substrate surface with a deposition plasma comprising a carbon source gas for a deposition period. Also provided is a vertically-branched graphene attached to a substrate surface, the vertically-branched graphene having a bulk portion extending from the substrate surface, the bulk having a degree of branching that increases with increasing distance from the substrate surface; and free-standing branched graphene having a proximal end and a distal end, the proximal end including a body portion, the body portion having a degree of branching, and the degree of branching increasing with increasing distance from the proximal end and decreasing distance from the distal end.)
