HYBRID CARBON NANOTUBE AND GRAPHENE NANOSTRUCTURES

摘要

A binder-free hybrid carbon nanotube and graphene nanostructure can be formed via a two-step chemical vapor deposition process. The method can include forming at least one graphene layer onto a surface of a conductive substrate by chemical vapor deposition temperature using a first mixture of methane and hydrogen and growing a plurality of carbon nanotubes onto the surface of the at least one graphene layer by chemical vapor deposition using a second mixture of ethylene and hydrogen to form the binder-free hybrid carbon nanotube and graphene nanostructure.
