Ultrasonic Sprayed Graphene Oxide and Air Sprayed Ag Nanowire for the Preparation of Flexible Transparent Conductive Films

Authors: Young-Hui Koa, Ju-Won Leeb, Won-Kook Choic, Sung-Ryong Kim

Abstract:

Transparent Conductive Films are currently dominated by indium tin oxide (ITO).  ITO however is a non flexible material.  Graphene on the other hand is not only flexible but extremely conductive.  Research conducted by the Department of Polymer Science and Engineering, Korea National University of Transportation,  Mirae Nanotech Inc. and Interface Control Research Center, Korea Institute of Science and Technology, researchers couple graphene with silver nanowires to create industrial grade transparent conductive films.  Contrary to prior research that only focuses on spin and bar coating techniques which have limitations to film size that can be produced the authors develop a multi step process that utilizes both conventional and ultrasonic spray technology that allow for large area transparent conductive films.
