Abstract: Methods for producing graphene-based products using graphene paste compositions. These methods include producing free-standing graphene foils, films, sheets, polymer supported graphene films, printed graphene structures, graphene features on polymer films, graphene substrates, and graphene metal foils. The methods impart functional characteristics, including corrosion protection and barrier properties to achieve selective enhancement of desired electrical, thermal, mechanical, barrier and other properties.
