A conducting polymer composite polyethylene glycol aniline polymer was prepared via chemical method. The corrosion inhibition of polyethylene glycol aniline composite on mild steel in 1.0N HCl has been evaluated by potentiodynamic polarisation, electrochemical impedance spectroscopy and weight loss measurements. The characterisation of the composite is done by FTIR. The inhibition efficiencies of these polymers increase with increasing concentration and immersion time. The electrochemical studies indicated the mixed nature of the composite. Results obtained from the chemical and electrochemical measurements are in good agreements.</p> https://journalofchemistry.org/paper/604/ PGAni Composite mild steel inhibition
