Abstract
The present invention relates to patterned graphite oxide films and methods to make and use same. The present invention includes a novel strategy developed to imprint any required conductive patterns onto self-assembled graphene oxide (GO) membranes.
Claims36
A method comprising the steps of:
- (a) selecting a graphite oxide membrane, wherein the graphite oxide membrane is a freestanding graphite oxide membrane;
- (b) forming a pattern on the graphite oxide membrane to form a patterned graphite oxide membrane, wherein the pattern is formed by reducing a portion of the graphite-oxide membrane to conducting reduced graphite oxide;
- and
- (c) forming a device that comprises the patterned graphite oxide membrane, wherein the step of forming the device comprises:
- cutting a pattern from tape, wherein the pattern of the tape is the same as the pattern of the patterned graphite oxide membrane, and
- operably affixing the tape to the patterned graphite oxide membrane, wherein the tape acts as a current collector.
