Rod‐Coating: Towards Large‐Area Fabrication of Uniform Reduced Graphene Oxide Films for Flexible Touch Screens

Abstract

A novel strategy is developed for the large-scale fabrication of reduced graphene oxide films directly on flexible substrates in a controlled manner by the combination of a rod-coating technique and room-temperature reduction of graphene oxide. The as-prepared films display excellent uniformity, good transparency and conductivity, and great flexibility in a touch screen.
