Discotic anthraquinones as novel corrosion inhibitor for mild steel surface

Liquid crystals are primarily known for their application in electro-optical devices and their application potential in preventing corrosion has rarely been explored. This report elucidates the application of a room temperature anthraquinone based discotic liquid crystal 1,5-dihydroxy-2,3,6,7-tetrakis(3,7-dime thyloctyloxy)-9,10-anthraquinone 3 (RTAQ) as a corrosion inhibitor on mild steel surfaces. It also attempts to bring out the importance of mesogenic organization towards inhibiting corrosion for metals. The aforementioned RTAQ exhibits, cathodic type of inhibition. The inhibition efficiency obtained for RTAQ was found to be 83.96% at a higher concentration of the inhibitor. The results obtained from quantum studies are in good agreement with the experimental studies. (C) 2021 Elsevier B.V. All rights reserved.
