Scholarcy highlights

  • Polymer nanocomposites are one of the most important applications of carbon nanofillers including graphene
  • The results obtained from these analyses showed the formation of homogeneous mixture with strong interaction between the constituents and evidenced by the shift in peak position in both Ultraviolet–visible spectrophotometry and Fourier transform infrared spectrum spectra
  • This review has highlighted some of the enhanced properties of polymer/graphene nanocomposites such as: Improvement in the mechanical, thermal and electrical properties of graphene-filled polymer nanocomposites which varies for different nanocomposites
  • (iii) The electrochemical stability of the PANI/graphene nanocomposites is much higher than the pure PANI or PANI/indium tin oxide composite electrode
  • (vi) Graphene-filled polymer nanocomposites showed superior thermal stability compared to the neat polymer
  • A 55% maximum increase in the modulus was obtained by adding only 0.1 wt % reduced graphene oxide, and an increase of 48% in tensile strength was achieved by adding 0.3 wt % rGO
  • The appreciable improvement in electrical conductivity is due to the formation of a conducting network by graphene sheets in the polymer matrix
