“…Regarding the research on improving the corrosion inhibition efficiency of gallic acid, future research is needed to develop more effective gallic acid-related synergistic mechanisms and to gain an in-depth understanding of the synergistic effects on metal corrosion inhibition, which can be used to design more efficient synergistic corrosion inhibition systems using molecular simulations and surface analysis (Kumar et al , 2018; Nagaraja et al , 2012). On the other hand, exploring material surface engineering and functionalization modifications, the adsorption of gallic acid on metal surfaces is not ideal, changing the metal surface morphology and improving the adhesion of gallic acid can also improve corrosion inhibition efficiency.…”

“…Adding nanomaterials to coatings is a relatively mature method to enhance the performance of the coating (Albrecht and Schneider, 1999). Nanomaterials can effectively fill the micropores and gaps of the coating and have the advantages of high specific surface area and small size, which can improve the compactness of the coating and prolong the penetration path of the corrosive medium between the coating and the substrate, to achieve the purpose of improving the physical barrier ability (Nagaraja et al , 2012; Mopon et al , 2021; Ostovari et al , 2009). In addition, many nanomaterials (such as metal oxides) have excellent mechanical stability, which can make up for the shortcomings of insufficient strength, poor continuity and poor wear resistance of coatings (Gao et al , 2018).…”

“…Therefore, the higher the gallic acid content of the phenolic film, the stronger the corrosion protection ability of the coating. Nagaraja et al (2012) prepared a nanoparticle-based on citric acid and Fe 3 O 4 using a co-precipitation method, silica modification and amino-functionalization of these particles. A gallic acid resin coating containing magnetic nanoparticles was formed by grafting gallic acid on the surface of the particles under alkaline conditions using the condensation reaction of formaldehyde and gallic acid.…”

“…Gallic acid is involved in metal protection as a raw material for the synthesis of one of the resin coatings. A common synthetic reaction is the ester exchange reaction: gallic acid exchanges with ester groups in the polymer to form new ester bonds and release small molecules that trigger the lengthening and crosslinking of polymer chains, the ester bonds formed to enhance the strength, chemical resistance and oxidation resistance of the coating (Proenca et al, 2022;Tan et al, 2020;Mopon et al, 2021). Researchers have explored a variety of resin systems, such as epoxy resins, polyesters, polyurethanes and acrylics.…”

Purpose Gallic acid is a substance that is widely found in nature. Initially, it was only used as a corrosion inhibitor to retard the rate of corrosion of metals. In recent years, with intensive research by scholars, the modification of coatings containing gallic acid has become a hot topic in the field of metal protection. This study aims to summarize the various preparation methods of gallic acid and its research progress in corrosion inhibitors and coatings, as well as related studies using quantum chemical methods to assess the predicted corrosion inhibition effects and to systematically describe the prospects and current status of gallic acid applications in the field of metal corrosion inhibition and protection. Design/methodology/approach First, the various methods of preparation of gallic acid in industry are understood. Second, the corrosion inhibition principles and research progress of gallic acid as a metal corrosion inhibitor are presented. Then, the corrosion inhibition principles and research progress of gallic acid involved in the synthesis and modification of various rust conversion coatings, nano-coatings and organic resin coatings are described. After that, studies related to the evaluation and prediction of gallic acid corrosion inhibition on metals by quantum chemical methods are presented. Finally, new research ideas on gallic acid in the field of corrosion inhibition and protection of metals are summarized. Findings Gallic acid can be used as a corrosion inhibitor or coating in metal protection. Research limitations/implications There is a lack of research on the synergistic improvement of gallic acid and other substances. Practical implications The specific application of gallic acid in the field of metal protection was summarized, and the future research focus was put forward. Originality/value To the best of the authors’ knowledge, this paper systematically expounds on the research progress of gallic acid in the field of metal protection for the first time and provides new ideas and directions for future research.

The present work reports a simple-economical procedure for the formation of silver nanoparticles by using controlled addition of concentration of cetyltrimethylammonium bromide (CTAB) as a capping agent, taking one-factor-at-a-time into consideration during the optimization process. Wet chemical method for silver(I) reduction has been used to synthesize nanoparticles using Andrographis paniculata. During the reaction, antioxidant property of biosystem reduces silver(I) to metallic silver(0) and CTAB encapsulates preventing the agglomeration, acting as barrier for the growth of the particle. The synthesised nanoparticle was characterised by powder X-ray diffraction, Fourier-transform spectroscopy, UV-Vis spectroscopy and SEM. The results showed that the silver nanoparticles doped with CTAB and its high crystallinity can be obtained using simple solvent method. The size of the nanoparticle by XRD, UV-Vis and SEM were found to be 0.897 nm, 45 nm and 18 to 43 nm, respectively. Tauc's plot of optical band gap suggested the movement of size towards quantum confinement for the synthesised nanoparticles was 2.25 eV. An antioxidant activity of A. paniculata and synthesized AgNps was studied by series of antioxidant assays. The nanoparticles were having antibacterial and antifungal activities when it was studied using Streptomycin and Ketoconazole as controls.
