Abstract
To address the inherent low conductivity of MoS₂, we developed a novel, simple, green, and scalable method for the preparation of graphene/MoS₂ composites using a laboratory-designed system. Through systematic optimization, the optimal preparation conditions were determined. Moreover, this method differs from traditional approaches that require high temperatures or hazardous reagents by enabling simultaneous exfoliation and compositing under mild conditions. Thus offering significant environmental and practical advantages. Comprehensive structural characterizations were conducted using XRD, Raman, SEM, TEM, HRTEM, and XPS. The results confirmed that bulk MoS₂ and graphite were successfully exfoliated into few-layer MoS₂ and graphene, respectively, which were subsequently composited to form a stable graphene/MoS₂ composite. The resulting material shows significantly enhanced electrical conductivity and charge transport, attributed to microstructure optimization and interfacial synergy. Overall, this study provides a practical and environmentally friendly strategy for improving the electrical conductivity of MoS₂, with promising potential for scalable production.
