Reinforcing anticorrosive properties of biobased organic coatings through chemical functionalization with amino and aromatic groups

Effects of TiO2 Nanoparticles on the Overall Performance and Corrosion Protection Ability of Neat Epoxy and PDMS Modified Epoxy Coating Systems

“…The absorption peak at 915 cm −1 of unmodified epoxy resin indicates the C-O deformation in the epoxide group, however, the decreased in the intensity of the peak at 915 cm −1 in the spectra of cured nanocomposite systems evincing the opening of the epoxide ring during curing reaction. Many studies have reported the curing reactivity of epoxy resin by using amine curing agents (Ansari et al, 2014;Moura et al, 2018). As reported by Ma et al, the curing state of epoxy resin with diamine curing agent at room temperature could be assigned to the disappearance of the absorption peak at 915 cm −1 in the cured neat epoxy (Ma et al, 2017).…”

Coatings and the environment: a review of problems, progress and prospects

“…According toOng et al (2021), corrosion is a natural process that destroys metal due to its reaction with corrosive environmental agents such as water and moisture [2]. Dealing with corrosion is a global phenomenon that bears heavily on the world economy; hence finding a cost-reducing, efficient, and environmentally compliant means of combating the menace is of concern to policymakers, industrialists, and researchers [13,14].Usingan organic coating to fight or inhibit corrosion has limited efficiency because it is permeable to water and oxygen due to its hydrophilic nature [15].…”

“…When the interfacial adhesion is strong, it protects the substrate against corrosion [11,54]. Adhesion is the most crucial property of organic coatings, without which other properties become useless and worthless.Lingner Moura et al [13]and Ammar et al [55]synthsised a fully organic coating system using epoxidised soybean oil and found corrosion-resistant properties [13,56]. The salt spray test shown by Soleimani et al [56] indicated that adding silica leads to increased anti-corrosionproperties up to 3 wt%, after which there is a decline in the anticorrosion property [56].…”

Evaluation of anti-corrosive properties of epoxidized rubber and siloxane hybrid coatings

“…One way to slow or decrease metallic corrosion is the use of surface coatings [1][2][3][4][5][6][7][8][9][10][11]. Among the various types of coatings used are organic coatings such as paints and varnishes, metallic, inorganic or organic-inorganic hybrids [10,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Chromatization is a common form of metal coating where the surface is coated with a layer of Cr 6+ compounds that are converted to trivalent chromium oxide, passivating the metal [5].…”
