Deployment of ammonium peroxydisulphate as oxidant and sodium salt of dodecylbenzene sulphonic acid as dopant as well as surfactant at ±5 ºC causes oxidative polymerization of aniline. Inclusion of CdO nanoparticles during oxidative polymerization yielded water soluble CdO-PANI composite. Formation of composite material was confirmed by comparing the results obtained in the FTIR, XRD and SEM spectral analysis with the reported values. Weight loss measurements by gravimetric method reveal the resisting adeptness of composite, 89% even after eight hours, against acidic environment. Open circuit potential measurement for 120 minutes exposes that raise in the concentration of composite shift the potential value to positive side. Potentiodynamic polarization and electrochemical impedance spectroscopy measurements also discloses the impervious nature of the synthesized material. Impregnable working environment can be provided by the prepared composite during industrial maintenance process.
