Nylon 6/with (0, 0.1, 0.2, 0.4, 0.6 and 0.8) wt. % MWCNTs films conductive polymers were prepared by electrospinning technique. Prepared films morphology test by SEM and the average fibers diameters measure statically was 140 nm for (nylon/0.4 wt. % MWCNTs film). The nanofibers films show enhancing the electrical conductivity by increase MWCNTs concentration, from (2.9 × 10−9 S/cm) for pure nylon film to (1.042 × 10−6 S/cm) for 0.8 wt. % MWCNT. The activation energy decreased with increasing the MWCNTs concentration, the activation energy was (0.068, 0.057, 0.0536, 0.0523, and 0.045 and 0.077) eV for (pure nylon, nylon/0.1, 0.2, 0.4, 0.6, 0.8% wt. % MWCNTs) films. The calculated result of 0.077 eV is even higher than the activation energy of the pure film which is 0.068 eV, this is may be due to changing the state of MWCNTs dispersion in the host polymer (nylon 6) as concentration of MWCNTs increased
