Mechanical Properties of Cu-GO Composite by Varying GO Mesh Sizes

Abstract

In this study, the copper-graphene oxide composites were prepared using low sintering temperature to investigate the effect of various mesh sizes of GO on Cu-GO composites. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman were conducted to elaborate the microstructure, diffraction pattern and disorder in the powders as well as bulk composites. Transmission electron microscopy (TEM) analysis was also carried out to further study the microstructural analysis of composites at the nano-scale level. By changing the mesh sizes of GO from lower to higher level, the tensile strength and hardness of Cu-GO composites were significantly enhanced due to better mixing of GO with higher mesh size. A fractograph analysis was also examined in detail to investigate the effect of various mesh sizes of GO on Cu-GO.
