Reduced graphene oxide-based Transparent Conductive Films: The preliminary review of reductant materials agent

Abstract

This review aims to present reductant materials that can be used to reduce the oxygen content of graphene oxide which supports the manufacturing of TCF so the development of TCF increases in the future. Reducing agents are separated into two types i.e. toxic materials and green materials. The method that was used to make TCF based on graphene oxide reduction in this paper review was drop-casting, spray coating, vacuum filtration, and spin coating. From the results of the study, it was found that the resistance sheet for each reductant material ranged from 3.4×109 to 52.2 Ω/sq. Besides, the use of toxic reductant materials still dominates as a reducing agent because it has a lower sheet resistance than the green reductant materials. Although there are still many challenges in the study of the transparent conductive film based on reduced graphene oxide, the information in this review is expected to contribute to the development of various optoelectronic devices, especially for the development of flexible, portable, and smart device.
