ABSTRACT
Optimum electrospinning conditions by using response surface methodology (RSM) have been recalled from previous work to produce MWCNTs/PAN nanofibril composites. The as electrospun fabrics have been heat treated. SEM have been used to analyze the produced fabrics before and after heat treatment took place The presence of MWCNTs reduces the produced fiber in diameter from 190 nm to 180 nm. Also, the hot pressed sample showed a reduction in fiber diameter and dielectric properties improved by adding MWCNTs as well as by heat treatment. Dielectric constant of 330 and conductivity of 100 S/cm were reported for the flexible MWCNTs/carbon nanofibril composite fabrics at 25000 Hz. Analytical approach has been used to evaluate the electric properties of a single nanofiber and nanofibril composite as function in its fabrics. Calculations of single nanofiber and nanofibril composites showed an increase in it electrical conductivity.
