Effect of Pre-Treatment Time On Graphene Nanosheets Produced by Exfoliation Method

Abstract

2D-Materials are the biggest candidates to take today’s electronic technology to a new point. In particular, graphene can find its place in many areas due to its unique properties. This has made the investigation of the factors that can affect the quality of graphene production up-to-date. In the present study, effect of pre-treatment time on graphene nanosheets produced was investigated. The structural analyses were carried out by X-ray diffraction spectroscopy (XRD), Raman spectroscopy, and Fourier Transform Infrared Spektrometresi (F-TIR). The morphological analyses of the surface were performed using scanning electron microscopy (SEM). The number of layers and crystallite of graphene nanoparticles was calculated and the results were compared with the literature. The results show that the pre-treatment time affects the structural properties of the graphene nanosheets produced by the exfoliation method and there is a more positive effect on exfoliated graphene quality for 20 min pre-treatment time.
