Abstract
The surface of mild steel was modified by the formation of Tween 60 Self-assembling nano
films to increase the corrosion inhibition ability. Formation of Self-assembled nano films takes place
when mild steel is immersed in well water in presence of 200 ppm of Tween 60 and 50 ppm of Zn2+ for
one day, shows 88 % corrosion inhibition efficiency. The modified surface was characterized by
polarization, cyclic voltammetry, FT-IR spectroscopy, SEM and EDS micrographs. Atomic Force
Microscopy confirmed the formation of lesser amounts of corrosion products on the Self-assembling
nano film protected surface. The nano film is found to be hydrophobic in nature. This is confirmed by
contact angle measurement.
