    摘要: The present invention provides methods of selectively removing one or more graphene layers from a graphene material by: (1) applying a metal to a surface of the graphene material; and (2) applying a hydrogen containing solution to the surface of the graphene material that is associated with the metal. The hydrogen containing solution dissolves the metal along with one or more layers of graphene associated with the metal, thereby removing the layer(s) of graphene from the graphene material. In some embodiments, the hydrogen containing solution is an acidic solution, such as hydrochloric acid. In some embodiments, the metal is zinc. In some embodiments, the methods of the present invention are utilized to selectively remove one or more layers of graphene from one or more targeted sites on the surface of a graphene material.

    摘要: Methods for producing macroscopic quantities of oxidized graphene nanoribbons are disclosed herein. The methods include providing a plurality of carbon nanotubes and reacting the plurality of carbon nanotubes with at least one oxidant to form oxidized graphene nanoribbons. The at least one oxidant is operable to longitudinally open the carbon nanotubes. In some embodiments, the reacting step takes place in the presence of at least one acid. In some embodiments, the reacting step takes place in the presence of at least one protective agent. Various embodiments of the present disclosure also include methods for producing reduced graphene nanoribbons by reacting oxidized graphene nanoribbons with at least one reducing agent. Oxidized graphene nanoribbons, reduced graphene nanoribbons and compositions and articles derived therefrom are also disclosed herein.
