Modification of natural gums for application as corrosion inhibitor
The utilisation of corrosion inhibitors is an extraordinary way to control metals’ corrosion; these are made out of natural or organic/inorganic compounds. By virtue, these organic/inorganic compounds significantly impact ecology, which has constrained the quest for more user-friendly inhibitors. Owing to their eco-friendliness, sustainability, and non-toxicity, natural gums are gaining more importance.
However, uncontrolled hydration rates, pH, and thermal instability are some of the problems associated with gums. The availability of hydroxyl groups and feasibility of the modification for introducing heteroatoms on the backbone of the gums, combined with various surfactants or salts of halides, can potentially be utilised. A general survey of the work done on some of the gums in their pure and modified form as an efficient corrosion inhibitor on different metallic substrates is examined in the new paper.
The survey has been published in Journal of Coatings Technology and Research, Volume 19, 2022.
