Abstract

Polyethylene oxide (PEO) / Polyvinyl chloride (PVC) blends with 2.5 wt% - 10 wt% polyaniline (PAni) loadings were fabricated with and without the presence of ferric chloride (FeCl₃). PEO/PVC/PAni and PEO/PVC/PAni-FeCl₃ conductive films were prepared by solution casting method using tetrahydrofuran as the solvent at ambient temperature. The electrical conductivity of the conductive films was analyzed and discussed in this paper. The study found that higher loading of PAni increased the electrical conductivity of the films and further improved with the addition of FeCl₃. The XRD analysis study supported the findings by revealing the modified structure of PAni, with FeCl₃as the oxidizing agent. The tensile strength, however, decreased with the addition of PAni and FeCl₃in the conductive films due to poor agglomeration of filler.
