Abstract:
The present investigation is on processing of a series of clay polystyrene nanocomposite (CPS) coatings containing
different adduct modified montmorillonite (Mt) for corrosion resistance coating applications. The corrosion
properties were studied using potentiodynamic and electrochemical impedance spectroscopy measurements in
3.5 wt% aqueous NaCl electrolyte. The CPS coatings offered enhanced corrosion protection for Aluminum 6061
alloy even at high clay loading (20 wt%). The order of their protection efficiency was CPS-AMt N Pristine
PS N Pristine Na+-Mt. Dispersion of Mt in the polystyrene matrix resulted in significant improvement of properties
such as corrosion protection, optical clarity, electrical conductivity and thermal stability
