Description
Summary:The present study provides a straightforward and practical approach to a chemical oxidation polymerization (COP) for the synthesis of polyaniline (PANI)-conducting polymer using ammonium persulfate (APS) as a redox initiator. The transition color changes of PANI were observed during the induction period and an increased rate of chemical reaction possessed a natural heat release (exothermic reaction), which is defined as heterogeneous precipitation polymerization. Attenuated total reflectance-Fourier transform infrared (ATR-FTIR), ultraviolet-visible (UV-Vis) spectroscopy and scanning electron microscope-energy dispersive mapping (SEM-EDX-mapping) were demonstrated to characterize their functional group, molecular electronic structure, and surface morphology-elemental distribution, respectively. To demonstrate PANI’s practical application in the conductive fabrics sector, cotton-type fabrics were then incorporated with the synthesized PANI and doped with various concentrations of para-toluene sulfonic acid (pTSA). Electro impedance spectroscopy (EIS) measurements revealed that the electrical conductivity of the fabrics was boosted significantly from 4.02 ± 6.38×10−7 S cm−1 of undoped PANI fabric to 5.39 ± 1.98×10−3 S cm−1 of 0.9 wt.% pTSA doped PANI fabric. This study can be adapted and tailored for the preparation of PANI via COP which may lead to applications in conductive fabrics.
