Abstract
AbstractConductive polymer film that possess stable electrical conductivity and good mechanical performance was prepared with the incorporation of polyaniline (PAni) and carboxymethyl cellulose (CMC) in grafted rubber (MG49) matrix was synthesized in this research study. PAni was synthesized through the chemical oxidation process while CMC was produced using the carboxymethylation reaction. Besides, conductive polymer films of MG 49/PAni/CMC were synthesized using ex‐situ polymerization. The optimum reinforcement of CMC in the polymer films was proven through UTM analysis at 8% CMC loading with tensile strength and Young Modulus of 12.1 and 630 MPa, respectively. The chemical interaction, crystallinity, thermal stability, and morphology behaviors of the conductive polymer films before and after chemical modifications were confirmed by FTIR, XRD, TGA, and SEM analyses. Chemical modification by the introduction of silane coupling agent into conductive polymer films significantly enhances the homogeneity of the composites by giving a stable and narrow range of electrical conductivity with the value of 6.931 × 10−7–8.768 × 10−7 S cm−1. As conclusion, the mechanical performance, and electrical conductivity of MG49/PAni/CMC(8%)‐TMMS is more homogenous and fulfils the requirements of conductive polymer film that can be potentially applied in the flexible conductors of stretchable electronics.
