“…In addition, R f of the carbon steel with cathodic protection was approximately 100 times that of the carbon steel without cathodic protection at 21 days. This reveals that the passive film on the carbon steel surface was strengthened after cathodic protection [54][55][56]. Therefore, the cathodic current generated by the cement-based thermoelectric device proved effective for the protection of carbon steel.…”

The thermoelectric cement-based materials can convert heat into electricity; this makes them promising candidates for impressed current cathodic protection of carbon steel. However, attempts to use the thermoelectric cement-based materials for energy conversion usually results in low conversion efficiency, because of the low electrical conductivity and Seebeck coefficient. Herein, we deposited polyaniline on the surface of MnO2 and fabricated a cement-based thermoelectric device with added PANI/MnO2 composite for the protection of carbon steel in alkaline chloride solution. The nanorod structure (70~80 nm in diameter) and evenly dispersed conductive PANI provide the PANI/MnO2 composite with good electrical conductivity (1.9 ± 0.03 S/cm) and Seebeck coefficient (−7.71 × 103 ± 50 μV/K) and, thereby, increase the Seebeck coefficient of cement-based materials to −2.02 × 103 ± 40 μV/K and the electrical conductivity of cement-based materials to 0.015 ± 0.0003 S/cm. Based on this, the corrosion of the carbon steel was delayed after cathodic protection, which was demonstrated by the electrochemical experiment results, such as the increased resistance of the carbon steel surface from 5.16 × 102 Ω·cm2 to 5.14 × 104 Ω·cm2, increased charge transfer resistance from 11.4 kΩ·cm2 to 1.98 × 106 kΩ·cm2, and the decreased corrosion current density from 1.67 μA/cm2 to 0.32 μA/cm2, underlining the role of anti-corrosion of the PANI/MnO2 composite in the cathodic protection system.

“…It would be desirable that some attention be given to the possibilities of application of CP in geothermal streams. Although the impressed current type of CP may be difficult to engineer into some of the complex geometries in the flow stream, the adoption of the simpler method of CP, that employs sacrificial anodes, would be worth considering [29].…”

“…Metals cannot be completely protected from corrosion. But it can be reduced in many ways, such as inhibitors [1][2][3][4][5][6][7][8][9][10] , cathodic protection [11][12][13] , and surface coating [14][15][16][17][18][19] . Mild steel is the most widely used shipbuilding material due to its good mechanical properties and low cost.…”

The present study deals with the synthesis and anticorrosion behavior of new modified graphene oxide. Superior corrosion resistance property was exhibited by graphene oxide and modified graphene oxide on mild steel and copper substrates. Along with the corrosion resistance behavior, the reinforcing nature of epoxy coating also improved. Graphene oxide was synthesized by Hummer’s method. Graphene oxide (GO) modified with ethanol extract of Kedrostis foetidissima (KF) plant leaves. Gas chromatography-mass spectrometry (GCMS) analysis was selected to identify the chemical constituents present in the plant. GO, KF, and modified GO (GO-KF) were characterized by Fourier transforms infrared spectroscopy (FTIR) and Field Emission Scanning Electron Microscope (FESEM). Corrosion protection behavior of epoxy coating on mild steel and copper with GO and modified Graphene Oxide were studied using, Salt spray test, Peel test, and Contact angle measurements. Results revealed that the modified GO sheets act as a good reinforcing agent for epoxy coating on mild steel and copper substrate in a 3.5% sodium chloride (NaCl) environment.
