Chemical grafting of aniline (ANI) onto wool fibre was carried out in aqueous acidic medium by using peroxosalts such as peroxodisulphate (PDS) and peroxomonosulphate (PMS) as an initiator for various [Monomer], [Initiator] and (fibre weight). It was observed that both R-h and R-g increased with increase in the concentration of each component. The chemical grafting was confirmed using FTIR spectroscopy, cyclic voltammetry (CV) and conductivity measurements.
