ADVANCEMENTS IN CELLULOSE/REDUCED GRAPHENE OXIDE COMPOSITES: SYNTHESIS, CHARACTERIZATION AND APPLICATIONS IN TRANSISTOR TECHNOLOGIES

Cellulose and reduced graphene oxide (rGO) composites have garnered significant attention for their potential in transistor applications, combining environmental sustainability with advanced electrical functionalities. This comprehensive review delves into the recent advancements in the synthesis, characterization, and application of cellulose/rGO composites, particularly in the realm of transistors. We explore various synthesis methodologies such as in-situ reduction, chemical grafting, and physical mixing, examining their effects on the composites' structural, chemical, and morphological properties. The review highlights the deployment of these composites in diverse transistor types including field-effect transistors (FETs), organic field-effect transistors (OFETs), and biosensors, emphasizing their design, functionality, and performance enhancements. Furthermore, we discuss strategies for material optimization such as tuning composite ratios, functionalization, and the integration of additional materials to boost electrical conductivity, charge carrier mobility, and sensitivity. The review also addresses the challenges of scalability, reproducibility, and long-term stability of cellulose/rGO composites, proposing future research directions for novel composite formulations, device architectures, and broader applications in flexible and wearable electronics. This analysis not only underscores the unique properties of cellulose/rGO composites but also their transformative potential in developing sustainable, high-performance electronic devices.
