Abstract
Provided are a graphene pattern and a process of preparing the same. Graphene is patterned in a predetermined shape on a substrate to form the graphene pattern. The graphene pattern can be formed by forming a graphitizing catalyst pattern on a substrate, contacting a carbonaceous material with the graphitizing catalyst and heat-treating the resultant.
Claims19
A graphene pattern comprising:
- 1-300 layers of graphene, which is a polycyclic aromatic molecule in which a plurality of carbon atoms are covalently bound to each other, and
- wherein the graphene is disposed on at least one surface of a substrate.
A process of preparing a graphene pattern, the process comprising:
- preparing a substrate on at least one surface of which a graphitizing catalyst pattern is formed;
- contacting a carbonaceous material with the substrate on which the graphene pattern is formed;
- and
- forming graphene on the graphitizing catalyst pattern through heat-treatment in an inert or reductive atmosphere,
- wherein the carbonaceous material is a carbon-containing polymer, a gaseous carbonaceous material or a liquid carbonaceous material, and
- wherein the carbon-containing polymer comprises at least one polymerizable functional group capable of forming a carbon-carbon double bond or triple bond.
