Preparation and Properties of Cu-Plated Graphene/Cu Composites

Abstract

This research delves into the realm of advanced composite materials, focusing on the preparation and mechanical properties of Cu-plated graphene (Cu@rGO) and its comparison with copper-plated graphite (Cu@G). The electroless plating method was employed to create Cu@rGO and Cu@G, which were subsequently mixed with copper powder and pressed, leading to the formation of Cu@rGO/Cu and Cu@G/Cu composites through vacuum sintering. A meticulous analysis of the mechanical properties, specifically hardness and compression strength, was conducted. Our findings reveal intriguing trends in the mechanical behavior of these composites. In Cu@rGO/Cu sintered bodies, the hardness and compressive strength exhibit an increase with rising Cu@rGO content, up to 1.2 wt.%. Conversely, under analogous conditions, Cu@G/Cu sintered bodies display a decrease in both hardness and compressive strength as the Cu@G content rises. This research not only contributes valuable insights into the preparation techniques of these composites but also sheds light on the nuanced mechanical responses associated with varying reinforcement phases. The implications of these findings extend to diverse engineering applications, paving the way for optimized designs and applications of graphene-enhanced copper composites.
