Abstract


Abstract

Self-assembling molecules form protective layers on metal surfaces Self assembled nanofilms of adipic acid, N-cetyl-N,N,
N-trimethyl ammonium bromide, Tween- 60, Sodium dodecyl sulphate and an  aqueous extract of  banana peel have been formed on  the  surface  of carbon steel by the immersion method. The formation of the nanofilms has been confirmed by Fourier Transform Infrared   spectral study and Atomic Force Microscopy Study. The corrosion inhibitive nature of the protective film has been estimated by the classical weight loss method and electrochemical study such as polarization study. The hydrophobic nature of the protective film has been investigated by measurement of contact angles of the protective films. The hydrophobic surfaces may find application in various exciting fields such as corrosion protection, raincoats, water proof surfaces and biomaterials. Copyright © 2017 VBRI Press.
