Applications of engineered graphene

A method of making graphene foil, the method comprising the steps of:

• a) providing a graphene paste composition comprising:
• i. graphene flakes, wherein the graphene flakes comprise engineered graphene;
• ii. one or more solvents;
• iii. one or more functional additives;
• and
• iv. one or more binders;
• and
• b) applying the graphene paste to a substrate to form a graphene foil on the substrate;
• and
• c) curing the applied paste;
• and
• d) optionally, releasing the graphene foil from the substrate to obtain a free-standing foil.

A graphene paste composition comprising:

• from 0.1 to 4.3 wt % of engineered graphene flakes;
• from 0.8 to 5 wt % of graphene, graphene oxide, reduced graphene oxide, and combinations thereof;
• from 60 to 95 wt % solvent(s);
• from 0 to 10 wt % polymeric resin binder(s);
• from 0 to 1 wt % surfactant and additive mixtures;
• and/or
• from 0 to 1.5 wt % of thermal or photo-curing curing catalyst(s).
