Abstract The present study investigated the potential antibacterial property of conductive cotton and polyester (PES) fabric coated with polyaniline (PANI). Phytic acid (10, 20, and 30% v/v) was used as a dopant. The fabricated fabric was produced via immersion technique with an immersion time of 30 minutes. The structural identification, conductivity, and morphological properties of prepared fabric were characterised with Fourier transform infrared spectroscopy (FT–IR), electrochemical impedance spectroscopy (EIS), and field emission scanning electron microscope (FESEM), respectively. The optimum conductivities of 2.28 × 10–4 S/m (for cotton) and 2.15 × 10–2 S/m (for PES) were recorded when doped with 30% (v/v) phytic acid. The antibacterial test showed that the fabricated fabric had relatively high antibacterial activity against K. pneumoniae, S. aureus, and E. coli strains. Keywords Polyaniline . Conductive fabrics .

nanoparticles with textile substrates to produce such fabricated fabric, this approach comes with its set of risks for its end users and the environment [1]. Alternatively, conducting polymers (CP) such as polyaniline (PANI) or sometimes can be referred to as aniline black can be deposited on the fabric surface through a chemical or electrochemical method to produce conductive fabric [2, 3]. PANI-coated fabrics are versatile, which are proven from their applications as ammonia sensor [4], electronic devices [5], and pr
