Recent Advances in Elastomeric Nanocomposites

Development of electrically conductive polymer nanocomposites for the automotive cable industry

“…However, the hybrid solution exhibits the highest effectiveness throughout the entire frequency range, which makes it appropriate for the applications under study. It is difficult to confront these results with data reported in the literature, since the latter were obtained at a higher frequency range (8)(9)(10)(11)(12)(13) GHz in comparison to 0.001-3GHz adopted in this work) and for much thicker samples [36][37][38] . Anyway, for nanocpmposites containing 5 wt% of CNT, the measured values of shield efficiency were of the order of |30| dB [37] .…”

“…Thermoplastic polymers used at the industrial scale are typically electrical insulators, however their electrical response can be modified by mixing them with electrically conductive materials [10] . In this context, the emergence of nanotechnology brought the potential of material modification by incorporation of nanoparticles with specific properties, allowing the development of composites with diverse properties at very low nanoparticle loads [11,12] . Some of the solutions explored are based on the use of carbon nanoparticles such as graphene and single-wall (SWCNT) or multi-wall carbon nanotubes (MWCNT), dispersed in a polymeric matrix at a concentration that allows the formation of a percolation network [13][14][15] , producing an electrically conductive nanocomposite [16][17][18][19] .…”
