“…Epoxy resin (EP) has been widely used as a general-purpose material to improve corrosion resistances due to its excellent chemical resistance and adhesion, good wear resistance and its flexibility. However, since the EP curing process is prone to coating defects such as holes, water channels, and gaps [ 14 , 15 ], corrosive particles may penetrate the coating and cause serious metal corrosion [ 16 ]. Adding conductive polymers and nano-fillers to the epoxy resin matrix can not only improve the electrostatic conductivity of the coating, but also promote the formation of a passivation layer at the metal/polymer interface, which can effectively prevent the penetration of corrosive particles.…”

In this work, a ternary TiO2/Graphene oxide/Polyaniline (TiO2/GO/PANI) nanocomposite was synthesized by in situ oxidation and use as a filler on epoxy resin (TiO2/GO/PANI/EP), a bifunctional in situ protective coating has been developed and reinforced the Q235 carbon steel protection against corrosion. The structure and optical properties of the obtained composites are characterized by XRD, FTIR, and UV–vis. Compared to bare TiO2 and bare Q235, the TiO2/GO/PANI/EP coating exhibited prominent photoelectrochemical properties, such as the photocurrent density increased 0.06 A/cm2 and the corrosion potential shifted from −651 mV to −851 mV, respectively. The results show that the TiO2/GO/PANI nanocomposite has an extended light absorption range and the effective separation of electron-hole pairs improves the photoelectrochemical performance, and also provides cathodic protection to Q235 steel under dark conditions. The TiO2/GO/PANI/EP coating can isolate the Q235 steel from the external corrosive environment, and may generally be regarded a useful protective barrier coating to metallic materials. When the TiO2/GO/PANI composite is dispersed in the EP, the compactness of the coating is improved and the protective barrier effect is enhanced.

“…This may lead to capsules collapse and poor mechanical stability and faster release and early loss of inhibitors. To ensure a stable release of inhibitors when required and for a longer life without loss of mechanical stability, the use of porous inorganic carriers has been proposed as an alternative [ 18 , 19 ].…”

Effectiveness of Epoxy Coating Modified with Yttrium Oxide Loaded with Imidazole on the Corrosion Protection of Steel

et al. 2021

The search for highly effective corrosion protection solutions to avoid degradation of the metallic parts is enabling the development of polymeric organic coatings. Of particular relevance, polymeric nanocomposite coatings, modified with corrosion inhibitors, have been developed to provide enhanced surface protection. In this work, yttrium oxide nanoparticles loaded with corrosion inhibitor (Imidazole), used as additives in the formulation of epoxy for coated on the steel substrate. The loading of Y2O3 with imidazole was confirmed by field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and Brunauer–Emmett–Teller analysis. UV-Vis analysis demonstrated the pH-sensitive behavior of the imidazole that helps in self-release when necessary. Electrochemical impedance spectroscopy (EIS) of the coated samples revealed that the coating modified with Y2O3/IMD provides better corrosion protection compared to coatings containing only Y2O3. XPS analysis validated the presence of an imidazole protective film on the steel substrate that enhanced the corrosion resistance of the coated samples

“…So, hybrid fillers were utilized to enhance the corrosion resistance of epoxy nanocomposites coatings as shown in Table 3. The corrosion properties of hybrid fillers epoxy nanocomposites coatings were analyzed using potentiodynamic studies, EIS studies, salt spray method, and adhesion strength determination in the literature [38][39][40][41][42][43][44][45][46][47][48][49][50][51]. The literature on hybrid fillers epoxy nanocomposites for corrosion protection is discussed in brief in this section.…”

Graphene oxide (GO) is a reinforcing filler material used in epoxy resin to make coatings for improving the corrosion resistance of epoxy. The synthesis methods of GO are discussed with their modification methods (covalently and non-covalently). The incorporation of GO in epoxy resin nanocomposites coatings shows the improved corrosion resistance and adhesion strength depends on the processing protocol and aspect ratio of GO. Modification of GO covalently and non-covalently and reinforced in epoxy nanocomposites coatings show the enhanced corrosion protection as compared to pure epoxy and epoxy/GO nanocomposites coatings due to improved dispersion of GO in an epoxy matrix. Inorganic nanofiller modified with GO as hybrid reinforcement in epoxy nanocomposites coatings shows improved corrosion resistance as compared to epoxy/GO nanocomposites. GO/inorganic hybrid filler reinforced in epoxy nanocomposites coatings are promising in terms of applications in the industry for long time corrosion protection.
