“…Just like other natural hazards (earthquakes, tornadoes, or hurricanes), corrosion can cause severe and expensive damage to everything from automobiles to infrastructure (pipelines, buildings, bridges, and military). The important method in corrosion control is incorporation of corrosion protective (inhibiting) coatings and/or inhibitors [1,2]. Organic coatings can retard corrosion through a barrier or inhibition mechanism.…”

Preparation and Anticorrosive Property of Soluble Aniline Tetramer

et al. 2019

Soluble aniline tetramer (AT) was successfully prepared by chemical oxidation method. Fourier transform infrared spectroscopy (FTIR) and ultraviolet-visible spectroscopy (UV-vis) were used to characterize its structure. The redox behavior of AT was identified through the electrochemical cyclic voltammetry studies. Then, the epoxy coating was prepared by using AT as inhibitor. Its anticorrosive property was evaluated by salt solution resistance test, polarization curve, and electrochemical impedance spectroscopy (EIS). Salt solution resistance test, polarization curves, and EIS measurements indicate that the obtained epoxy anticorrosive coating, containing 1.0% AT, exhibits remarkably enhanced corrosion protection properties on Q235 steel electrodes as compared to pure epoxy anticorrosive coating without AT. The significantly improved anticorrosion performance may be owing to the redox behavior of the AT, adsorption and inhibition effect of AT on Q235 steel surface, as well as synergistic curing effect by AT and polyamide.

“…In the case of 304 stainless steel, the phase angle as well as the impedance modulus decrease and increase, respectively, as the frequency value decreases. Therefore, in this case, one time constant that describes the presence of an electrochemical reaction is observed [44]. In addition, the lack of a siloxane coating means that a plateau appears in the high frequency range (Figure 6).…”

“…In the range of high-frequency values, sample R2 shows the lowest phase angle (θ), which is equal to almost -90 • . This indicates that the coating deposited on sample R2 is the thickest or/and is the most uniform, i.e., it shows the best dielectric properties [39][40][41][42][43][44]. Additionally, in the range of low-frequency values, the phase angle for this sample is the highest.…”

The earlier obtained organosilicon derivatives of rapeseed oil were used for the production of coatings protecting steel surface against corrosion. Vegetable oils have been hitherto used for temporary protection of metals against corrosion, while thanks to the synthesis of appropriate organosilicon derivatives, it is now possible to create durable protective coatings. Due to the presence of alkoxysilyl groups and the use of the sol-gel process, the coatings obtained were bonded to the steel surface. The effectiveness of the coatings was checked by electrochemical methods and steel surface analysis.

“…These structures are organic molecular assemblies which spontaneously form dense and ordered layers with a thickness of single nanometers on appropriate substrates [6][7][8][9]. Depending on the molecular design, SAMs provide a way to tailor surface properties such as wetting [10,11] adhesion [12,13], friction [14][15][16] and antimicrobial [17] and corrosion properties [18][19][20]. Their high attraction is also driven by the simple preparation procedure, the reproducible film quality and stability of the monolayer.…”

The Effect of Physicochemical Properties of Perfluoroalkylsilanes Solutions on Microtribological Features of Created Self-Assembled Monolayers

The presented article shows the influence of concentration of perfluoroalkylsilanes in solutions on tribological properties of self-assembled monolayers (SAMs) deposited on three surfaces with different silicon content in the millinewton load range. The SAMs were created using the liquid phase deposition (LPD) method with 1H, 1H, 2H, 2H-perfluorodecyltrichlorosilane (FDTS) and (3, 3, 3-trifluoropropyl) trichlorosilane (FPTS) solutions, for which viscosity and surface tension were estimated. Deposited layers were analyzed in terms of thickness, coverage, wettability, structure and coefficient of friction. The obtained results demonstrated that SAMs created on the silicon-incorporated diamond-like carbon (Si-DLC) coatings possess the best microtribological properties. Systems composed of perfluoroalkylsilane SAM structures deposited on Si-DLC coatings are highly promising candidates as material for microelectromechanical applications.
