An attempt has been made to develop nano emulsion coatings based on Azadirachta indica (neem oil) as a replacement of organic solvent based coatings system in surface finishing industry for environmental protection, and for public health and safety. Neem oil nanoemulsion was prepared using neem oil, tween 20. A mean droplet size ranging from 31.03 - 251.43 nm, was formulated for various concentrations of oil and surfactant. The stable emulsion ratio was taken for the study. Coatings on the steel surface were done using electrophoretic deposition method. Different combinations of stabilizers were tried and characterized using AFM. The AFM images confirmed the formation of nano emulsified coatings on steel.
