Abstract

Freestanding, paper-like films of reduced graphene oxide (rGO) containing trace amounts of polymers are fabricated by an operationally simple, cost-effective, and environmentally friendly gel-film approach. The films, which can have a large area, display ultrahigh strengths and toughnesses as well as high electrical conductivities.

Keywords: films; gel-film transformation; graphene; graphene oxide; hydrogels.
