    • In some embodiments, the present invention provides methods of making graphene- carbon nanotube hybrid materials. In some embodiments, such methods generally include: (1) associating a graphene film with a substrate; (2) applying a catalyst and a carbon source to the graphene film; and (3) growing carbon nanotubes on the graphene film. In some embodiments, the grown carbon nanotubes become covalently linked to the graphene film through carbon-carbon bonds that are located at one or more junctions between the carbon nanotubes and the graphene film. In some embodiments, the grown carbon nanotubes are in ohmic contact with the graphene film through the carbon-carbon bonds at the one or more junctions. In some embodiments, the one or more junctions may include seven-membered carbon rings. Additional embodiments of the present invention pertain to graphene-carbon nanotube hybrid materials that are formed in accordance with the methods of the present invention.
    • 在一些实施例中,本发明提供了制造石墨烯 - 碳纳米管混合材料的方法。 在一些实施例中,这样的方法通常包括:(1)将石墨烯膜与衬底相关联; (2)将催化剂和碳源施加到石墨烯膜; 和(3)在石墨烯膜上生长碳纳米管。 在一些实施方案中,生长的碳纳米管通过位于碳纳米管和石墨烯膜之间的一个或多个连接处的碳 - 碳键变成共价连接至石墨烯膜。 在一些实施方案中,生长的碳纳米管通过一个或多个连接处的碳 - 碳键与石墨烯膜欧姆接触。 在一些实施方案中,一个或多个连接点可以包括七元碳环。 本发明的另外的实施方式涉及根据本发明的方法形成的石墨烯 - 碳纳米管混合材料。
