“…In sulfuric acid solution, for the case of 0.01 M 3TMA, an increase in the R p values with time untill 8,400 ohms approximately was observed, and for 0.01 M 3TMA in sulfuric acid, the average R p value was 3,000 ohms approximately. These values were reached after 16 h and remained until 24 h. An increase in the R p values is indicative of a decrease in the corrosion rate (Silva et al , 2012; Nicho et al , 2011). The best corrosion performance for all immersion times in both the media was for the 0.01 M 3TMA, presenting R p values higher than the blank.…”

“…The fact that the loop diameter (resistance values) decreased indicates an increase in the corrosion rate (Nicho et al , 2011), and when the diameter increases, the corrosion rate decreases. An increase and decrease in resistance values on our systems were observed (Table III), indicating that the ultrathin layer of oxide on the copper surface is instable (protective and not protective, and vice versa).…”

Purpose The purpose of this study was to examine the copper protection against corrosion using 3-thiophenemalonic acid (3TMA). Design/methodology/approach The heterocyclic organic molecule was tested experimentally as a corrosion inhibitor of copper in two different concentrations (0.01 M and 0.001 M) in 0.5 M solutions of sodium chloride and sulfuric acid by AC electrochemical and DC techniques. Findings Results showed that the organic compound was adsorbed chemically on the copper surface, and the inhibitions mechanism was both anodic and cathodic. The corrosion mechanism was under mixed control: charge transfer from metal to the environment through the double electrochemical layer, and diffusion processes. Practical implications This inhibitor could have application in water cooling systems. Originality/value The results of this paper showed that 3TMA could be used for reducing corrosion rates of copper in solutions of sodium chloride and sulfuric acid.

Thiophene (Th), 3-hexylthiophene (3HT) and their nanocomposites with TiO 2 were electropolymerized on Al1050 electrode by chronoamperometic technique. Different concentrations of Th and 3HT homopolymers and their nanocomposites with TiO 2 (2% in total content) were characterized by attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), energy dispersion Xray analysis (EDX) and electrochemical impedance spectroscopy (EIS). The capacitive behaviours of modified electrodes were calculated from Nyquist, Bode-magnitude, Bodephase and Admittance plots. The optimum conditions of capacitive behaviours of homopolymers (PTh and P3HT) and their nanocomposite films of PTh/TiO 2 and P(3HT/TiO 2 ) were electrocoated on an Al1050 electrode by chronoamperometric technique. The anti-corrosion tests for homopolymers and nanocomposite films were examined in 3.5% NaCl solution. The EIS and Tafel extrapolation results were comparatively studied. In all cases, polymer and nanocomposite films have protective behavior of Al1050 against corrosion. P(3HTh)/TiO 2 nanocomposite films gave the highest protection effeciency (PE) = 98% because the amount of defects was much lower than that for the P(3HTh), PTh and PTh/TiO 2 films.

“…Intercalated MMT or RGO in polymers decrease the gas and moisture penetration rate because their high aspect ratio and layer structure, which lowers the corrosion rate. The second category is the introduction of specific interaction from the organic coating layer to metal to enhance bonding between organic coating and metal [5,[14][15][16]. This prevents penetration of corrosive materials to the surface of metal and gives rise to higher anticorrosion stability.…”

“…Schauer [20] studies the corrosion behavior of PANI/epoxy on iron using Iron/PANI/epoxy layered structure and finds that phase separation between PANI and epoxy layer ending up with intercoat delamination that lowers the protection efficiency of the organic coating on iron. In order to achieve stronger bonding between the organic coatings and metals, researchers have synthesized coating materials with different functionalities such as phosphoric acid [14,15], hydroxyl group [16], and polyionic liquid [5]. Interfacial bonding between the organic coating layer and the metal is, therefore, increased and anticorrosion property is improved.…”

Enhanced Corrosion Protection of Iron by Poly(3-hexylthiophene)/Poly(styrene-co-hydroxystyrene) Blends

et al. 2018

Corrosion of iron in NaCl solution is significantly reduced by poly(3-hexylthiophene) (P3HT)/poly(styrene-co-hydroxystyrene)(PS-co-PHS) blended coating layers, especially at elevated temperature. The interaction between sulfur (in P3HT) and hydroxyl group (in PS-co-PHS) leads to enhanced miscibility between P3HT and PS-co-PHS and results in improved thermal stability upon thermal treatment. Adhesion force between iron and the coating layer is increased with increasing hydroxystyrene ratio as revealing by the adhesion test (ASTM 3359). Anticorrosion properties from electrochemical experiments indicate great improvement over the P3HT/PS blend. Protection efficiency (PE) of P3HT/PS-co-PHS blend on iron increases and corrosion rate (mils per year, MPY) decreases upon thermal treatment, making P3HT/PS-co-PHS blend an excellent corrosion inhibitor and adhesion promoter material to the iron, especially with good thermal stability.
