Polypropylene Carbon Nanotubes Nanocomposites: Combined Influence of Block Copolymer Compatibilizer and Melt Annealing on Electrical Properties

(a) Electrical conductivity in the 1 Hz–67 GHz frequency range. The lowest conductivities are measured for the pure SEPS and PP matrices. With 2% wt CNT, the conductivities range from to  S/m at low frequencies, depending on PP content. The highest conductivity is obtained at 5% SEPS (PP93). (b) Electrical conductivity in the 1.7 GHz–67 GHz frequency range.
