Direct Assembly of Graphene Oxide on Flexible Substrates for Highly Transparent Electrodes via the Langmuir-Blodgett Technique

초록

The surface activity of graphene oxide (GO) offers an ideal building block upon which to construct two-dimensional (2D) nanostructures via side-by-side assembly strategies. In this work, we demonstrate the Langmuir-Blodgett assembly of GO into a 2D film with a carbon monolayer thickness on a PET substrate over a large area. After the reduction of the GO films at a low temperature, transparent flexible conducting films were realized. Our straightforward route for preparing graphene-based transparent films provides a controlled strategy to coat graphene monolayers on flexible substrates.
