A comparative review of processing methods for graphene-based hybrid filler polymer composites and enhanced mechanical, thermal, and electrical properties

Abstract

Graphene-based hybrid filler polymer composites represent a significant advancement in materials science and engineering due to graphene’s remarkable mechanical, thermal, and electrical properties. This comprehensive review systematically evaluates both traditional (e.g., mechanical and solution mixing) and modern fabrication techniques (e.g., in situ polymerization, chemical modification, electrospinning, and layer-by-layer assembly) employed in the synthesis of these composites, comparing their effectiveness in enhancing material properties such as strength, thermal stability, and conductivity. Emphasizing the synergistic interactions between graphene and other fillers within polymer matrices, the paper discusses mechanisms that lead to superior composite performance. A thorough survey of the literature highlights successful examples where these composites have demonstrated significant advancements in mechanical, thermal, and electrical properties. Three detailed tables summarize findings from published studies, illustrating the enhanced properties and achievements at various filler concentrations across different preparation methods. The review concludes by outlining future research directions aimed at optimizing graphene hybrid filler polymer composites for broader scientific and industrial utilization. By consolidating current knowledge and providing a practical resource, this review aims to guide researchers and practitioners in harnessing the full potential of these advanced materials.
