Written-in conductive patterns on robust graphene oxide biopaper by electrochemical microstamping

Abstract

The silk road: By employing silk fibroin as a binder between graphene oxide films and aluminum foil for a facile, highly localized reduction process, conductive paper is reinvented. The flexible, robust biographene papers have high toughness and electrical conductivity. This electrochemical written-in approach is readily applicable for the fabrication of conductive patterned papers with complex circuitries.

Keywords: conductive paper; electrical conductivity; graphene; mechanical properties; silk.
