Scalable Production and Thermoelectrical Modeling of Infusible Functional Graphene/Epoxy Nanomaterials for Engineering Applications

“…Functional polymer nanocomposites with pliable properties are considered to be exciting matrices for composites in structural applications by virtue of their considerably enhanced electrical and thermal conductivity. , These materials combine the characteristics of polymer matrices such as low cost and versatile processing techniques with the unique features of the nanomaterials, including high aspect ratio, large surface areas as well as multifunctional properties. − Thermosetting epoxy resins remain the primary material choice for industrial and structural fields, including coatings, electronic devices, adhesives, marine systems, and aerospace parts due to the unique blend of properties they offer such as high tensile strength and modulus, thermal stability, chemical and corrosion resistance. , However, epoxy materials have significant drawbacks, including their brittle nature and sensitivity to defects, as well as poor electrical and thermal conductivity. Epoxy-based nanocomposites require further research and development to overcome these disadvantages and allow implementation within commercial applications.…”

“…Moreover, their flat sheet morphologies are more prone to roll, scroll, wrinkle and twist than few-layered graphene nanomaterials. Graphite nanoplatelets (GnPs), which correspond to partially exfoliated graphite, are a relatively new class of nanomaterials that are gaining increasing attention as a more viable alternative to single-layer graphene due to their low cost, scalability, and ease of processing. , …”

“…Graphite nanoplatelets (GnPs), which correspond to partially exfoliated graphite, are a relatively new class of nanomaterials that are gaining increasing attention as a more viable alternative to single-layer graphene due to their low cost, scalability, and ease of processing. 10,14 Previous studies have testified the significant influence of GnPs addition into a host epoxy matrix to achieve improved physical and functional properties 15−24 when incorporated appropriately. As-prepared graphene-epoxy composites (GECs) may then be used as is or further implemented into FPR composites, leading to multiscale optimization to enable smart self-sensing composites.…”

Graphene‐Based Composite Foams with Tunable Porosity for Ultra‐Sensitive Low‐Pressure Applications

“…In short, using the conductance instead of the resistance is a better way of characterizing the signal of a sensor. [29,30] Under compressive forces, the pores and cell walls of the foam collapse and get closer to the adjacent cell walls. The graphene sheets are sandwiched between the cell wall and lie on the cell surfaces as per the foam morphology.…”
