Design of novel superhydrophobic aniline trimer modified siliceous material and its application for steel protection

Design, synthesis, and evaluation of high‐performing anticorrosive polyurethane coatings with inbuilt redoxable oligomeric aniline segments

“…Electrochemical impedance spectroscopy (EIS) is the eminent test for the investigation of corrosion resistance of thin films and various types of coatings. In this study, films are characterized by frequency domain in a wide range from 10 5 to10 −2 Hz and the resultant data are fitted with the respective circuit which has elements such as polarization resistance conductance and capacitance 68–70 . The anti‐corrosive behavior of EPUU coatings was characterized by electrochemical impedance spectroscopy in the frequency domain including Nyquist and bode plots in a 3.5% sodium chloride solution.…”

“…In this study, films are characterized by frequency domain in a wide range from 10 5 to10 À2 Hz and the resultant data are fitted with the respective circuit which has elements such as polarization resistance conductance and capacitance. [68][69][70] The anti-corrosive behavior of EPUU coatings was characterized by electrochemical impedance spectroscopy in the frequency domain including Nyquist and bode plots in a 3.5% sodium chloride solution. However, all the samples were tested after 45 h of immersion in the salt solution for 25 wt% and 30 h of immersion for 12.5 wt% due to the initial coating was highly resistive to make electron transfer across to the surface of the steel.…”

Facile Fabrication of Superhydrophobic Surface from Fluorinated POSS Acrylate Copolymer via One-Step Breath Figure Method and Its Anti-Corrosion Property

“…Tafel curves and EIS data are two main methods for the evaluation of material corrosion situation [45]. For comparison, acrylic resin films without the 7F-MAP-POSS were prepared by casting commercial acrylic resin (YP2226, Shanghai yoo-pont chemical industry Co., LTD., Shanghai, China) solution with the same volume and concentration onto a clean Q235 iron plate under atmosphere condition.…”

“…Furthermore, the inhibition efficiency (IE) was consistent with the evolution of i corr value, the result of which were 96.44% (AC), 99.22% (FPOSS10-FAC), 99.83% (FPOSS20-FAC) and 99.98% (FPOSS25-FAC), suggesting the addition of 25 wt % 7F-MAP-POSS produced the best shielding effect for Q235 substrate. situation [45].
