In this article, the author reports a new class of Organic-inorganic Nano-composites (OINCs) prepared by electrophoretic codeposition (EPD) of electro-activated organic polymer matrix together with the inorganic nano- particles under the influence of dc electric field, followed by appropriate curing. The process utilises a commercial grade bifunctional epoxide polymer duly electro-activated and converted into an aqueous emulsion in which the nanoclay particulates (NP) of Montmorillonite (MMT) and Bentonite (BNT) are dispersed and ultrasonicated. The novel process permits the higher NP content beyond 8% by weight of the polymer in aqueous bath. EPD process parameters like, bath composition, applied voltage, time and electrode spacing, have been studied. The author highlights some results in one of the studies [7] showing significant improvement in physico-mechanical and dielectric properties, viz., adhesion (no peeling as per ASTM D-3359-87), corrosion resistance (after 800 h. exposure to 4% salt fog), increase in dielectric strength by about 2 times (36kV/mm), volume resistivity by 10 times (4.3 x 1016 ?cm) at 8% by weight MMT loading, as compared to the pristine polymer.
