摘要

In this study, high-strength, lightweight, and electrically conductive nanocomposites are synthesized by incorporating reduced graphene oxide (rGO) into low-density polyethylene (LDPE) through extrusion moulding. The surface morphology analysis reveals that the rGO/LDPE nanocomposites have rougher, layered structures for higher rGO concentrations due to coagulation. Structural modifications and significant absorption peaks corresponding to the bending and stretching vibrations of specific functional groups are detected. Enhanced crystallinity with the addition of rGO is observed where 3% rGO/LDPE has shown the highest crystallinity of 44%. Enhancement in thermal stability is evident by higher degradation temperatures and less weight loss, delaying degradation by 34 K for 2% rGO/LDPE nanocomposite. 70% enhancement in Young’s modulus is achieved in this case. Moreover, the DC electrical properties of the nanocomposites have exhibited a significant increase in current density (J) with higher rGO concentrations, indicating the formation of a continuous conductive pathway. Validation of the experimental results through percolation theory indicates that the nanocomposite is a disordered 2D–3D hybrid conductive network. As the temperature is increased, an increase in J is observed owing to the improvement of the mobility of charge carriers. However, excessive rGO concentration (for 3% rGO/LDPE) has reduced the J due to agglomeration of rGO. These findings suggest the potential use of these nanocomposites in electronics applications.
