Abstract

This study dealt with fabrication of conducting polyaniline-cellulose acetate(PANI/CA)nanocomposites through electrospinning different concentrations of PANI in CA dissolved in DMF/ acetone mixture (3:1 v/v) at a flowrate of 2 mL/h and 4 mL/h. The presence of characteristics functional groups of PANI in the FT-IR spectra of PANI/CA nanocomposites proved the embedment of PANI in CA. The highest conductivity rcorded was 0.005416± 0.00054 S/m obtained from solution B (0.1% PANI wt/v) electrospun with solution flowrate of 2 mL/h. The smallest average fiber diameter was obtained from solution B (0.1% PANI wt/v) spun at flowrate of 2mL/h while the largest average fiber diameter was obtained from solution E (2% PANI wt/v) spun at flowrate of 2 mL/h. The highest and the lowest percentage of bead were the fibers electrospun from the control solution at 2mL/h and 4mL/h, respectively. Solution feeding flowrate has a high significant effect on the conductivity of the nanocomposite while the concentration and the interaction of the two factors have a very highly significant effect.
