Abstract
In this paper, Reduced graphene oxide (RGO) was synthesized from graphene oxide (GO) with environment friendly method by using polyphenol that contained a phytoextract of fresh potato as reducing agent. Graphene oxide was prepared by modified Hummer’s method. The extent of reduction was studied by varying volume reducing agent 20, 40 and 60 ml respectively. The resulting product have been characterized by Fourier transform spectroscopy, Raman spectroscopy and X-ray diffraction. Then RGO was composited with PEDOT:PSS copolymer for improve electrical property. The electrical property was also measured by four-point probe. From the electrical property test, the PEDOT: PSS composite with RGO has a lower electrical resistance. The above results confirm that preparation of RGO and electrical improvement were success.

Thank you very much for your nice presentation! For my questions based on electrical properties, I would like to know: how much different electrical conductivites between as-prepared composite and pristine one? Also, you selected this kind of PEDOT:PSS copolymer, is it the best in this field?
In this research, I studied electrical property that related to electrical resistance. Which materials have low electrical resistance, they are higher conductivity than materials with high electrical resistance. From the result, I found that the elctrical resistance of PEDOT:PSS copolymer is 6.61 megaohm. On the other hand, electrical resistance of copolymer that composite with reduced graphene oxide is 3.04 megaohm. And for this research, I think PEDOT:PSS copolymer is the most suitable option because PEDOT:PSS copolymer is transparent and flexible. Which is a very necessary property for preparation of transparent elctrode in smart display.
Thank you.
