Polymer/clay nanocomposite films were prepared by electrodeposition from aqueous dispersions of acrylic anodic electrophoretic resin (AAER) and Na+-montmorillonite (MMT). The characterization results using XRD, SEM and TEM indicated well-dispersed MMT platelets in the composite films prepared. Mono-disperse-like hexagonal MMT platelets were observed when the MMT loading in the resin matrix was low. The ideal dispersity achieved was thought to be the result of aqueous compatibility between AAER molecules and MMT platelets and of the water-involved process as well. FTIR study proved the interaction between AAER and MMT and the intercalated or exfoliated morphology. Thermal stability, tensile modulus and strength, storage modulus and glass transition temperature of the polymer/clay nanocomposite films were effectively improved compared to those of the virgin AAER film.
