The use of particulate nanomaterials as fillers has enabled very large interphases to be created at low loadings . Facilitating significant property transfer that can not only improve the mechanical properties of the resultant nanocomposite, but a variety of other functions too, e.g., electrical, thermal and tribological . Nanocarbon based fillers boast strong mechanical properties, as well as high thermal and electrical conductivities. Making them attractive prospects for multifunctional improvements to epoxy resins. They can be synthesised in various dimensions, e.g., 0D fullerenes, 1D carbon nanotubes (CNTs), and 2D graphene nanoplatelets (GNPs), with each generating a unique interphase geometry. However, their graphitic surfaces adhere poorly to the surrounding epoxy matrix resulting in poor interfacial stress transfer and high phonon and electron scatter . Furthermore, these weak interactions mean the fillers preferentially interact with one another, leading to fullerenes aggregating, CNTs bundling, and GNPs restacking. To counter these issues, there has been extensive work on functionalising the nanocarbon surfaces, to promote a better interphase through chemical compatibilities.
