investigation of the power between cinnamon essential oil macro and nanoemulsions as green corrosion inhibitors

Trying to reduce the corrosion problems as a critical menace for all industries, emphasizing the urgent need to increase responsible r d centers, the development of high inhibition efficiency green inhibitors with new treatment strategies, and innovative interventions on a global scale is a necessary challenge. here, a new type of cinnamon essential oil macro and nanoemulsions as green, sustainable, and low-cost corrosion inhibitors were introduced. the prepared macro and nanoemulsions were characterized with the dls technique. the macro and nanoemulsion were used for investigating c1018 steel corrosion within acidizing media due to the implementation of corrosion inhibitors continuing to be a significant concern in chemical sectors. to our knowledge, there is no comparative study on the effect of nano and macro‐emulsions of cinnamon essential oil on the corrosion resistance properties. the results obtained show that the nanoemulsion of the cinnamon essential oil due to the lower particle size of the oil nanoemulsion droplet and more effective interaction with the metal surface could act as an effective inhibitor compared to the macroemulsion sample for the corrosion protection of c1018 steel in hcl media. as can be seen from scanning electron microscopy (sem) images that were used to confirm the vital role and activity of the cne in reducing the corrosion rate, it is clear that the cne inhibitor can inhibit the dissolution of iron, thereby reducing the rate of corrosion and which means an affording better protection against corrosion in 0.1 m hcl.
