Popis: Conducting polymer (CP) is one of the multifunctional materials that can be manipulated into wide applications across all sciences fields, such as chemistry, biology, physics, material science and engineeringThe demand of using the flexible and lightweight electronic devices has inspired us to use fabrics as a substrate to produce a smart material. The incorporation of conducting polymer (CP) onto fabrics displays a huge potential and promising research as it is considered under developed. Here, we present the exploration of the incorporation of polyaniline (PANI) into a polyester fabric, producing a conductive fabric with the enhanced properties: potential anti-infection. In this study p-toluene sulfonic acid (pTSA) is used as a doping agent and different weight percentage of pTSA (0.3, 0.6 and 0.9 wt%) are used to discover the effect of different weight percent of dopant on PANI-EB. The conductive PANI is then embedded on polyester fabric by immersion technique for 15 minutes (optimal time). The characteristics of the fabrics are then characterized using FTIR, UV-Vis, SEM and EIS. For the anti-infection properties, agar disc diffusion method is used. The morphology of all the samples, showed no significant changes. The optimum conductivity of the PANI fabric is found to be at 0.9 wt% which is 6.89 x 10-5 S/cm. Additionally, the inhibition zone are showed on the PANI fabric with the thickness of 10 mm ±1.5. Taken together all the results, it is concluded that PANI fabric has been successfully fabricated by immersion technique.
