A method of doping of Haemoglobin (Hb) into Polyindole (PIN) was developed to accomplish the haemoglobin polyindole composite (HPC) with improved electrochemical performance and maintained thermal stability. The scheme of doping was accomplished through cationic surfactant assisted dilute polymerization of indole (0.12 mol dl^-1) in the presence of ferric chloride oxidant (1.85 X 10-2 mol dl^-1) augmentation with indispensable weight of Hb (1%; w/w). The formation of HPC was ascertained through scanning electron microscopy (SEM), thermogravimetric-differential thermal analysis-differential thermogravimetry (TG-DTA-DTG) and electrochemical impedance spectra (EIS). Working electrode was derived from PIN and HPC in the presence of sulphonated polysulphone binder in graphite matrix. The specific capacitance (Cs Fg⁻¹) of PIN and respective HPC (1%w/w) electrodes has been 21.60 and 39.40 respectively. In order to have further imminent into the consequence of Hb on the stability, the SEM images have been recorded before and after polarization experiments. The rendered enhanced impact, thermal stability and remarkable potential as anticorrosive coating.
