Centimeter-sized dried foam films of graphene: Preparation, mechanical and electronic properties

Abstract

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 © -1. © 2012 WILEY-VCH Verlag GmbH & Co.
