Abstract

Introduction: The graphene has received a great attention because
of its extraordinary characteristics of high carrier mobility, excellent thermal conductivity, high optical transmittance, and superior
mechanical strength. Developing a simple methods with the property of producing large quantities of high-quality graphene have
become essential for electronics, optoelectronics, composite materials, and energy-storage applications. Materials and Methods: In
this study, the simple one step and efficient method of grinding
was used to produce few-layers graphene nanoflakes from graphite.
Different microscopic (TEM, SEM, and AFM) and spectroscopics
(XRD, XPS, and Raman) charactrization tools were used to test
the quality of the resultant graphene nanoflakes. Results: The produced nanoflakes showed no traces of oxidation due to the grinding
process. In addition, the applicability of the obtained nanoflakes as
potential supercapacitor electrodes was investigated. For that purpose, thin films of the few-layer graphene nanoflakes were developed using spray coating technique. In terms of both transparency
and conductivity, the prepared films showed equivalent properties
compared to those prepared by more complex methods. The electrochemical properties of the prepared electrodes showed high
specific capacitance of 86 F g_1 at 10 A g_1 with excellent stability.
The electrodes sustained their original capacity for more than 7000
cycles and started reducing to 72 F g-1 after 10000 cycles. Conclussions: The method provides a simple, efficient, versatile, and
eco-friendly approach to low-cost mass production of high-quality
graphene few-layers. The electrochemical stability and flexibility of
the developed thin films indicated that the films could be used as
electrodes in a wide range of electronic applications.
