Abstract
Official abstract text for this publication.
A process includes layering a graphene layer onto a polymer layer to form a composite film.
First claim
Opening claim text (preview).
What is claimed is: 1 . A process, comprising: layering a graphene layer onto a polymer layer to form a composite film. 2 . The process of claim 1 , wherein the layering is performed in a solution. 3 . The process of claim 2 , wherein the graphene layer floats on the solution, wherein the layering includes causing the polymer layer to lift the graphene layer from the solution. 4 . The process of claim 2 , wherein the solution has a neutral pH. 5 . The process of claim 1 , comprising layering a second graphene layer onto the composite film. 6 . The process of claim 5 , wherein the second graphene layer is added to the polymer layer on a side of the composite film, the side being opposite the graphene layer. 7 . The process of claim 5 , wherein the second graphene layer is added to a side of the composite film, the side being the same side as the graphene layer. 8 . The process of claim 5 , comprising coupling a third graphene layer to the composite film. 9 . The process of claim 1 , comprising coupling a second polymer layer to the composite film. 10 . The process of claim 1 , wherein the graphene layer includes several layers of graphene. 11 . The process of claim 1 , wherein the graphene layer is a single layer of graphene. 12 . The process of claim 1 , wherein the graphene layer includes islands of graphene held together by van der Waals forces. 13 . The process of claim 1 , wherein the graphene layer covers an entire side of the polymer layer.
