Ultrasmooth transparent conductive hybrid films of reduced graphene oxide and single-walled carbon nanotube by ultrasonic spraying

Abstract

A simple and industrially scalable ultrasonic spraying was used to prepare an ultrasmooth transparent conductive films (TCFs) of graphene oxide (GO) and single-walled nanotube (SWNT). The hybridization of two-dimensional reduced GO (rGO) and one-dimensional SWNT on polymethylmethacrylate (PMMA) film resulted in flexible TCFs. The vapor treatment of nitric acid on the rGO/SWNT film revealed a significant decrease in sheet resistance. The peeled-off rGO/SWNT/PMMA film from the glass substrate exhibited an exceptionally low surface roughness of 0.54 nm with a light transmittance of 85% and a sheet resistance of 153 MD. The sheet resistance of the TCFs films changed little under 500 bending. (C) 2016 Elsevier B.V. All rights reserved.
