Abstract
In this work, we have grafted Polyaniline (PANI) on polyester fabric by Chemical oxidative polymerization of aniline monomer using Ammonium per sulphate (APS) as oxidant and Sodium salt of dodecyl benzene sulfonic acid (DBSA) as a co-dopant. For better deposition and adhesion of PANI on the surface of polyester fabric, low-pressure radio frequency (RF) oxygen (O2) plasma treatment is applied to the fabric prior to grafting of PANI. Characterization of conducting fabrics is done using ATR-FTIR Spectroscopy, Scanning electron microscopy (SEM), Contact angle measurement, X-ray Photoelectron spectroscopy (XPS) and Sheet resistance measurement. It is observed that O2 plasma treatment enhances uniformity of grafting, conductivity and gives strong interfacial bonding of PANI on the surface of polyester fabric. O2 plasma-treated fabrics followed by grafting with PANI was then investigated for detection of ammonia gas.
