“…Under mild conditions, the sol-gel method allows the mixing of two or more dissimilar phases to form hybrids [32].In sol-gel methods, the production of homogenous nano-sized materials of complex composition can be easily produced with a cost-effective production [33]. From the name of the method, the sol represents the chemical transformation of the liquid into a gel phase and subsequently transition into solid oxide material [34]. The three-dimensional network structure of sol-gel is prepared by freeze-drying and calcination [35].The synthesis of TiO2 NPs from sol gel method is a wet chemical technique that mostly used in ceramic engineering and material sciences [15] Heshmapour and his coresearcher use sol-gel method for the synthesis of TiO2 and then mixing with ceramic and PANI.…”

“…In addition to ceramic and PANI, modification of TiO2 other nanocomposites such as wastederived polymeric biosurfactant and hyperbranched polyethyleneimine polymer template (HPEI) have also been conducted using sol-gel method [24] [36]. The sol-gel method can produce highly pure crystalline nanoparticles powder at low synthesis temperature without requiring a washing step since it is a waste-free synthesis and [37] [34] Another alternative method to synthesize TiO2 is through the instantaneous synthesis method. As the name of the process suggests, the synthesis of TiO2 is only in one-step process.…”

Titanium dioxide (TiO2) is widely used because of its good biocompatibility and stability. Various methods were used to prepare TiO2 by using chemical, biological, and physical methods. In this paper, the currents methods to prepare TiO2 were evaluated either with or without using plant extract. The average particle size produced for different methods of technique and its application was also analyzed. Chemical methods use toxic chemical while physical methods such as gamma produce high energy and using biological method with plant extract is more environmentally friendly. This review gives an up-to-date summary of TiO2 produced using various synthesis methods with the focus on their particle sizes properties. Recent publications on this topic were extracted from related journals obtained from Science Direct online database from the year 2010 to 2021. Preparation methods, average particles sizes, and the applications of the synthesized TiO2 were evaluated and further discussed in this review. It was found that TiO2 of smaller particle sizes were obtained when synthesized without using plant extract. Furthermore, many researchers tend to combine TiO2 with other materials or composites to be mixed with polymers for various purposes of application especially wastewater treatment application.

“…Merging the properties of organic materials and inorganic ones led to novel hybrid organic–inorganic corrosion resistance coatings, which become one of the most effective techniques of surface protection. , The most widely applied hybrid inorganic–organic material is modified organosilanes (adhesion promoter). , They are a great replacement for chromate and phosphate coatings because they are non-toxic and inexpensive as well as environmentally safe. These compounds have a general formula R n SiX 4– n , where R is an organic group, for example, alkyl, glycidoxypropyl, amidogen, or others, and X is a hydrolyzable group (alkoxy: −OMe or −OEt).…”

Eco-friendly Silane-Based Coating for Mitigation of Carbon Steel Corrosion in Marine Environments

2023

Losses from corrosion contribute roughly 3–5% of the gross domestic product of developed nations, and among the many methods used to avoid corrosion, using silane-based coatings is seen to be of the biggest importance due to their low toxicity and superior adhesive qualities. It is essential to develop an anti-corrosion coating that is efficient, economical, and eco-friendly. The corrosion resistance and durability of various silane-based coatings such as 1,2-bis(triethoxysilyl)ethane (BTSE), bis[3-(triethoxysilyl)propyl]tetrasulfide (TESPT), and vinyltrimethylsilane (VTES) for carbon steel 1018 substrates were investigated in a high-salinity environment (4.5 wt % NaCl). The corrosion resistance performance was evaluated via potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques. Results revealed that the TESPT film (pH ≈ 7) has the best corrosion resistance performance on the carbon steel surface in the aggressive chloride environment, that is, 99.6%. The high corrosion resistance of the TESPT film is due to the hydrophobic nature of this silane, which leads to the formation of a stable and dense film. These results were supported by X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) analyses.

The incorporation of organic corrosion inhibitors into waterborne coatings is optimized in this work. Herein, p‐coumaric acid (4‐hydroxycinnamic acid) is modified by a butyl radical and its effectiveness as an anticorrosive free inhibitor in solution is confirmed by potentiodynamic polarization (PP). The molecule is then successfully incorporated into waterborne polymeric binders by employing different polymerization techniques in dispersed media. Whenever possible, the inhibitor is also blended into the bare latexes to compare the effect of the incorporating method. The anticorrosion performance of the obtained coatings is tested and compared by electrochemical analysis. Promising results are obtained for the coatings produced by semibatch emulsion polymerization even at the low concentration of 1.5 mg of inhibitor g−1 latex. The intact control coating without inhibitor shows an impedance of up to 106 Ω and a phase angle of 72° after 1 h of immersion in the corrosive medium, meanwhile the coating with inhibitor shows higher values, 106.7 Ω and 80°. Active corrosion inhibition is observed in the coating with inhibitor in which a defect has been done, as the impedances drop to 103.9 Ω after 24 h of immersion in the saline solution while in the control scratched coating it drops to 103.6 Ω.
