Centimeter-Sized Dried Foam Films of Graphene: Preparation, Mechanical and Electronic Properties
A simple method to fabricate centimeter-sized thin films of graphene oxide (GO) is developed via drying the relative liquid film supported by a rigid frame. After reduction, centimeter-sized thin reduced GO films are obtained, and the maximum transparency is 75.8% while the minimum sheet resistance is 920 Omega square(-1).
