Conductive fabrics were prepared by using polyaniline (PANI) doped with p–toluene sulfonic acid (pTSA) as the acid dopant. Initially, different concentration of polyacrylonitrile (PAN) ranging from 0.5 to 3.0 wt.% was added to PANI–pTSA solution by a chemical blending process and the blends were then embedded onto the polyester (PES) fabric through an immersion method. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), and scanning electron microscope (SEM) were employed to characterize the chemical structural, crystallinity and morphology of PANI/PAN fabric, respectively. Electrochemical impedance spectroscopy (EIS) measurement revealed that the electrical conductivity value of the composite fabric was dropped by two orders of magnitude from 4.19×10−4 S cm−1 to 6.40×10-6 S cm-1 with the initiation of 0.5 wt.% of PAN. The conductivity values were maintained at the same order of magnitude (10-7 S cm-1) after the addition of 2.0 wt.% of PAN or higher. The conductivity behaviour of composite fabrics at room temperature and the function of temperature (298K to 393K) were also investigated. Thermogravimetric analysis (TGA) suggested that the thermal stability of the composites improved in 5.11% with the addition of 0.5% PAN in the composite fabrics. [ABSTRACT FROM AUTHOR] |
