Abstract
The present disclosure relates to a process for producing sheets of a composite material comprising a graphene film arranged on an amorphous carbon substrate, the process comprising the steps of: a) providing a lignin source and an aqueous solution to form a composition, b) depositing the composition on a metal surface, c) heating the composition on the metal surface to form the composite material.
Claims21
A process for producing a composite material comprising a graphene film arranged on an amorphous carbon substrate, the process comprising the steps of
- a) providing a lignin source and an aqueous solution to form a composition
- b) depositing the composition on a metal surface
- c) heating the composition on the metal surface to form the composite material on the metal surface.
A composite material formed as flakes having an average size of at least 1 μm2, wherein the flakes comprises
- a substrate comprising amorphous carbon having a first side oppositely arranged a second side, and
- a graphene film arranged on at least the first side of the substrate.
(canceled)
An intermediate composite material comprising
- a substrate comprising amorphous carbon having a first side oppositely arranged a second side, and
- a graphene film arranged on at least the first side of the substrate wherein one side of the substrate is arranged on a metal surface.
