Electrically conductive fabric coated with polyaniline: physicochemical characterisation and antibacterial assessment

摘要

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 spectros-copy (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.
