“…Phytic acid (PA) molecule has six phosphate groups which can combine with metal cations; it is an environmentally friendly rust inhibitor. Graphene (G) is the thinnest two-dimensional (2D) carbon material; its own unique nanostructure endows its perfect impermeability to any atoms and molecules under ambient conditions, and so G could be used as an excellent functional filler in anticorrosion coatings (Gu et al, 2015;Bai et al, 2021;Mu et al, 2021). In our previous research, we have confirmed that the original iron ions absorbed on rusty carbon steel surfaces could be transformed by PA, and a dense film was formed with the reaction of PA and rust (Xu et al, 2021).…”

A graphene modified epoxy surface tolerant coating was prepared, and the corrosion performance and rust conversion mechanism of the prepared composite coating on rusty carbon steel substrate was investigated. Scanning electron microscope (SEM), X-ray powder diffractometer (XRD), and infrared (IR) spectrum were used to confirmed the iron rust conversion performance by the reaction of phytic acid and rust. electrochemical impedance spectroscopy (EIS), polarization curve, and salt spray test were used to evaluate the corrosion resistance of low surface treatment coatings. Results indicated most of the rust were dissolved and transformed with the reaction of phytic acid and rust on the rusty carbon steel; graphene could effectively improve the compactness and protective performance of the epoxy surface tolerant coating.

“…Nanosized materials have a challenge of agglomeration because of the presence of Van der Waals forces; hence, they stick together to form lumps [42,23,44]. They also tend to agglomerate due to enormous surface energy and strong polarity [45].These characteristics must be dealt with by modifying the surface and thus making the surface available for use in various other applications [38].…”

“…Because if nanomaterial surfaces are not modified, they will inhibit instead of enhancing polymer nanocomposites' properties [46].Nanosized materials could be modified and functionalised through several methods, such as surfactant-assisted modification, polymer grafting, and silane grafting [48]. According to Mu et al [44], modification of graphene significantly improves graphene dispersion in polymer coatings resulting in a better barrier effect in corrosion prevention [44].Agglomeration usually leads to poor distribution of the nanomaterials in the polymer composite. Sometimes, it is so severe that the inorganic nanomaterial's simple mechanical mixing and agitation may not effectively fix it [48].…”

Coatings are surface protection applications providing decorative, functional, or both applications on their applied substrates. Its application on substrates can be ingases, liquids, or solids. The environmental issues stemming from coating application, especially those from petroleum base feedstock, cannot be over-emphasised.This paper is poised to examine the merits of biodegradable synthesised polymeric coatings from a renewable source (plant seed oils).Using seed oil as a feedstock for organic coatings involves functionalising the seed oil to create a reactive site for polymerisation.The use of nanoparticles also helps to fine-tune coatings properties, and sometimes they provide thermal stability, adhesion, chemical resistance, electrical conductivity, anticorrosive, antimicrobial, hydrophobicityproperties, etc.

“…Epoxy (EP), exhibiting superb adhesive properties with metallic substrates, has long been recognized as an excellent corrosion-resistant coating material [ 3 , 4 , 5 ]. The strong adhesivity of EP with metals originates from its ring-opening reaction of the epoxide groups, but the downsides are lack of flexibility and low thermal stability.…”

Epoxy (EP) was copolymerized with polyamic acid (PAA, precursor of polyimide (PI)) with termanil monomers of (1) 4,4′-Oxydianiline (ODA) and (2) pyromellitic dianhydride (PMDA) individually to form (PI-O-EP) and (PI-P-EP) copolymers. The FTIR spectrum of PI-O-EP copolymerization intermediates shows that some amide-EP linkages were formed at low temperature and were broken at higher temperature; in additoin, the released amide was available for subsequent imidization to form PI. The curing and imidization of the amide groups on PAA were determined by reaction temperature (kinetic vs. thermodynamic control). In PI-P-EP, the released amide group was very short-lived (fast imidization) and was not observed on FTIR spectra. Formation and breakage of the amide-EP linkages is the key step for EP homopolymerization and formation of the interpenetration network. PI contributed in improving thermal durability and mechanical strength without compromising EP’s adhesion strength. Microphase separations were minimal at PI content less than 10 wt%. The copolymerization reaction in this study followed the “kinetic vs. thermodynamic control” principle. The copolymer has high potential for application in the field of higher-temperature anticorrosion.
