Graphene nanoplatelets/Epoxy Nanocomposites: A Review on Functionalization, Characterization techniques, Properties, and Applications

English (OpenAlex)

Graphene nanoplatelets (GNPs) have received immense attention from the global scientific research community in the 21st century due to their two-dimensional planar structure, high surface area, functionalization abilities, and notable thermal-mechanical-electrical properties. When appropriately integrated into polymer matrices, graphene nanosheets improve the mechanical performance of polymer under static and high-strain rate loading. On the other hand, surface modification of GNPs through functionalization enhances dispersibility and interfacial strength of GNPs/polymer composites. Computational methods for GNPs-based nanocomposites considering micromechanical and multiscale modeling were also developed to predict their thermo-mechanical and electrical properties. These nanocomposite materials have been identified as having a wide range of applications in aerospace, automotive, construction, biomedical, energy storage, sensor, and textiles. In this review paper, recent advances of GNPs/epoxy nanocomposites, including their functionalization processes, characterization techniques, production methods, properties, and potential applications, have been comprehensively explained. Furthermore, it attempts to provide a complete framework for researchers by summarizing and evaluating the extensive literature on these nanocomposite materials.
