Abstract	Describes application of polymer coatings with various pH values, containing cellulose nanofibers and a corrosion inhibitor to carbon steels for corrosion inhibition. Researchers measured the polarization resistance of scratches made to the prepared coatings in a corrosive solution. They observed that resistance of the scratched coatings was largely dependent on the pH of the polymer. The scratched polymer coating prepared at pH 11.4 exhibited a significant increase in polarization resistance just after immersion, and was the highest measured after a 24 h corrosion test.
