Graphene nanoplatelets/epoxy nanocomposites: A review on functionalization, characterization techniques, properties, and applications

Abstract

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.

Graphene and Its Derivatives: Synthesis and Application in the Electrochemical Detection of Analytes in Sweat

“…As a result, the following description of synthesis techniques concentrates mostly on these characteristics. Graphene’s production methods and comprehensive characterisation have been described elsewhere in the literature [ 38 , 39 ]. The top-down (destruction) and bottom-up (construction) techniques for graphene production are the two major methodologies [ 40 ].…”

The synergistic impacts of hybrid nanofillers of graphene nanoplatelets/carbon nanotubes on curing behavior of an epoxy‐vinyl ester interpenetrating polymer network nanocomposite coating

“…24,25 Furthermore, the usage of organic and inorganic nanofillers in the IPN materials, for example, nanoparticles carbon allotropes such as carbon nanotubes (CNTs) and carbon nanofibers (CNFs), graphene nanoplatelets (GnPs), metal oxide based nanofillers, nanoclays, and so on, have been widely considered by several researchers during the last two decades. [26][27][28][29][30][31] Nowadays, among the types of nanofillers, incorporating CNTs [32][33][34][35][36][37][38][39][40] and GnPs [41][42][43][44][45][46][47][48][49][50] is of special interest in the fabrication of thermoset nanocomposites. The usage of CNTs can surpass the mechanical, thermal, and electrical features of IPN materials owing to their great aspect ratio, one-dimensional nanostructures, small mass density, and extraordinary properties.…”

Thermal, mechanical, thermo‐mechanical and morphological properties of graphene nanoplatelets reinforced green epoxy nanocomposites

“…By adding GNPs in polymers, it improves strength, stiffness, and resistance to fracture of resulting composite material. [3][4][5] GNPs exhibit high electrical, mechanical, and thermal properties, thermal conductivity of single-layer graphene can be up to 5000 W m À1 K À16 and can be used in applications like energy storage devices and sensors. [7][8][9][10][11] For dispersion of graphene nanoplatelets (GNPs), three primary methods are employed: solution blending, in situ polymerization, and melt processing.…”
