Abstract

In view as corrosion inhibitor, silk protein hydrolysate (SPH), a water-soluble hydrolysate obtained from silk protein (biopolymer) exhibits
excellent protection to mild steel in 1 N H2SO4, especially at low concentration levels. Weight loss analysis propose a maximum efficiency
for 10 ppm SPH at 303 K. Potentiodynamic polarization measurement revealed its functioning as a mixed-type inhibitor with enhanced
polarization resistance. The best fits observed with Langmuir isotherm suggested the inhibitor-metal interaction to occur via physisorption
mechanism. Surface examination through SEM (EDXS), water contact angle, AFM, FT-IR and Raman spectroscopy confirmed the
formation of protective film.
