Ultra-High Resolution Conductive Traces Flexible Biocomposites by Resist Stenciling

In a method of making a conductive structure， a reducing agent is applied to a region of a sheet of graphene oxide composite paper for a predetermined amount of time. The reducing agent is removed after the predetermined amount of time so as to expose a region of reduced graphene oxide disposed in the sheet of graphene oxide composite paper. A conductive structure includes a sheet of graphene oxide composite paper. At least one region on the sheet of graphene oxide composite paper includes reduced graphene oxide.
