“…Organic chemicals adsorb on metallic surfaces and slow down the rate of corrosion. Therefore, many organic compounds were used as corrosion inhibitors [4][5][6][7][8]. Chalcones are a significant group of natural compounds and their pharmacological properties have attracted a lot of attention in recent years.…”

The present work involved preparation of new polyimides drived from chalcone derivative, chalcone compound prepared from reaction of 4-amino acetophenone with vanillin, and then the chalcone which have amine group reacted with maleic anhydride to produce the corresponding amic acid. The synthesized amic acid compound was introduced in ring closure reaction by acetic anhydride and sodium acetate to produce maleimide. The new maleimdie was polymerized by free radical polymerization to yield homo and copolyimide with two vinylic monomers (acrylonitrile and methyl acrylate). The structures of synthesized compounds and polymers have been confirmed by physical properties and spectroscopy measurements (FT-IR) Fourier Transform Infrared Spectroscopy, ( 1 H-NMR) nuclear magnetic resonance. In addition, antibacterial activity of polymers was examined against two types of bacteria, namely Gram-negative and Gram-positive and gives good results in bacterial inhibition. Likewise, the anticorrosion activity of polymers was studied by using potensiostat measurements in acidic medium and the polymers give inhibition efficiency (94%).

This study systematically reviews the progress of research on the corrosion inhibition effects of organic compounds on carbon steel since 2002, using the CiteSpace bibliometric tool. Through the analysis of 2,264 articles from the WOS (Web of Science) and Scopus databases, our team delved into aspects such as annual publication volume, authors, institutions, countries and keywords which helped identify the current research focus in this field. In particular, the protective efficacy of organic compounds on carbon steel in acidic environments has been highlighted. It is evident that the integration of coating technology, the development of organic compound derivatives and the extraction of green organic compounds have emerged as new research hotspots in this field. This study not only comprehensively evaluates the means and methods of assessing the corrosion inhibition performance of new organic compounds but also further specifies the main directions for future research in this field. These include composite organic coatings, targeted development of new organic compounds, development and application of green organic compounds from plants and corrosion inhibition mechanisms of organic compounds on other metal materials. This study not only provides a thorough and in-depth review of the history and current status of this field but, more importantly, clarifies specific directions for future research in this area. The aim of this research is to provide strong theoretical support and practical guidance for subsequent researchers, promoting future development of this field.

“…For this reason, scientists have tended to solve this major problem in different ways, and one of these ways is the use of corrosion inhibitors. [1][2][3][4][5] Several synthetic organic molecules [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] were utilized to inhibit the corrosion of iron and steel in strong acidic media. Usually, these molecules containing heteroatoms and multiple bonds.…”
