“…This behaviour probably resulted from the two competitive phenomena-dispersive matrix strengthening by GN and deterioration of overall composite bonding due to increased viscosity of epoxy resin. Similar problems were reported by a number of other researchers [33][34][35]. The lowest flexural strength of the composite with 0.5 wt% GN can be explained by alterations in the preparation process-the nanoadditives were not sonicated for the composites containing more than 0.5 wt% of GN.…”

The aim of this study was to investigate potential applications of milled secondary carbon fibres as a primary filler in conductive polymer composites. The examined composites were based on epoxy resin, milled secondary carbon fibres and selected carbon nanoadditive used as a secondary conductive filler.Three kinds of nanopowders were tested: multiwalled carbon nanotubes, graphene nanoplatelets and graphitized carbon black. In the first stage of the experiment, composites with different percentages of carbon fibres were examined in order to determine the electrical conductivity and percolation threshold. Subsequently, the most conductive composition (70% of carbon fibres, r = 9.05 S cm -1 ) was modified by adding nanofillers. The addition of carbon nanotubes caused more than twofold increase in in-plane conductivity to 20.18 S cm -1 . The composites with graphene nanoplatelets showed deterioration of properties due to strongly increased viscosity of a binder with graphene. Small loadings of graphitized carbon black had a minor positive impact on the electrical conductivity and mechanical properties of composites.

“…70,163 As the single-layer graphene has a thermal conductivity of up to ~5300W/mK at room temperature, it is expected that a small amount of graphene can significantly improve the thermal conductivity of polymer matrices, 57 which was confirmed by several works. 70,163 As the single-layer graphene has a thermal conductivity of up to ~5300W/mK at room temperature, it is expected that a small amount of graphene can significantly improve the thermal conductivity of polymer matrices, 57 which was confirmed by several works.…”

“…Then GO/PA6 composites were performed with MB chips and commercial virgin PA6 chips using a twin screw 8 extruder. Other methods also have been reported, such as higher shear mixing (calendaring), 57 which have been used for polymers like epoxy resins, but have been not reported in preparation graphene/PA6 composites. This approach was also adopted by Liu et al 103 They produced FG/PA6 composite fibers using in situ polymerization and melt spinning methods, and found an obviously improvement of tensile strength and Young's modulus.…”
