Polyethylene oxide (PEO)/polyvinyl chloride (PVC) blends with 2.5– 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 tensile properties, electrical conductivity and structure/morphology of the conductive films were analysed and discussed in this paper. The results indicated that the tensile strength and elongation at break decreased but the Young’s modulus increased with PAni loading. Meanwhile, PEO/PVC/PAni-FeCl3 conductive films showed lower tensile strength and Young’s modulus but higher elongation at break in comparison with PEO/ PVC/PAni conductive films. The agglomeration of PAni at higher loadings was revealed by SEM study. However, this study found that higher loading of PAni increased the electrical conductivity of the films and further improved with the addition of FeCl3. The FTIR study revealed the structure of the films with the effect of PAni as filler and FeCl3 as the oxidising agent.
