The present work involved preparation of new polyimides drived from chalcone derivative, chalcone compound prepared from reaction of 4-amino acetophenone with vanillin, and then the chalcone which have amine group reacted with maleic anhydride to produce the corresponding amic acid. The synthesized amic acid compound was introduced in ring closure reaction by acetic anhydride and sodium acetate to produce maleimide. The new maleimdie was polymerized by free radical polymerization to yield homo and copolyimide with two vinylic monomers (acrylonitrile and methyl acrylate). The structures of synthesized compounds and polymers have been confirmed by physical properties and spectroscopy measurements (FT-IR) Fourier Transform Infrared Spectroscopy, ( 1 H-NMR) nuclear magnetic resonance. In addition, antibacterial activity of polymers was examined against two types of bacteria, namely Gram-negative and Gram-positive and gives good results in bacterial inhibition. Likewise, the anticorrosion activity of polymers was studied by using potensiostat measurements in acidic medium and the polymers give inhibition efficiency (94%).

“…[I corr (uncoated) − I corr (coated)]/I corr (uncoated) × 100 where I corr (uncoated) and I corr (coated) are the corrosion current density values without and with inhibitor, respectively. The decreasing inhibition performance as the temperature of the solution rises might be explained to an increase in the mobility of the inhibitor molecules, resulting in a reduction in the contact between the inhibitor molecules and the carbon steel surface [16][17].…”

The corrosion inhibiting properties of the new furan derivative 5- (furan-2-ylmethylsulfonyl-4phenyl-2,4-dihydro [1,2,4] triazole-3-thione in acidic solution (1.0 M HCl) were explored utilizing electrochemical, surface morphology (AFM), and quantum chemical calculations approaches. The novel furan derivative 5-(furan-2-ylmethylsulfonyl-4-phenyl-2,4-dihydro [1,2,4] triazole-3-thione shows with an inhibitory efficiency value of 99.4 percent at 150 ppm, carbon steel corrosion in acidic medium is effectively inhibited, according to the results. The influence of temperature on corrosion prevention was studied using adsorption parameters and activation thermodynamics. The novel furan derivative creates a protective layer over the metallic surface that separates the metal from harsh acid solution and thereby protects it from destructive disintegration, according to the AFM study. The experimental findings are supported by the theoretical method of density functional theory (DFT) at the B3LYP/6-311 ++G basis set for inhibitor.

“…Organic compounds containing heteroatoms such as oxygen, sulfur, or nitrogen atoms in their structures are often electropolymerized to produce effective polymeric coatings against corrosion. These compounds are selected based on their large molecular weight, functional polarity (such as -C=O, C=N), and extensive connections in aromatic rings, allowing them to adsorb on alloy surfaces [18]. There are many studies on the electropolymerization process to protect alloys from corrosion [19][20][21][22][23].…”

In the current study, a novel conductive polymer poly 6-((4 acetylphenyl) carbamoyl) cyclohex-3-ene-1-carboxylic acid (PACC) was created by polymerized 6-((4 acetylphenyl) carbamoyl) cyclohex-3-ene-1-carboxylic acid (ACC) monomer using the electropolymerization process. The resulting polymer was characterized using Fourier Transform Infrared Spectroscopy (FTIR). The ability of this polymer to protect the alloy from corrosion was studied at temperatures ranging between 298 and 328 K. The ability of these coatings to stop corrosion on the surface was assessed by measuring the corrosion potential (Ecorr) and the corrosion current (icorr) using a potentiostat. Adding nanoscale metal oxides (zirconium dioxide (ZrO2) and magnesium oxides (MgO)) enhanced the efficiency of this polymeric coating. The protection efficiency of the polymer alone was 77.5%; this efficiency increased to 85.0% and 99.7% in the presence of nano ZrO2 and MgO, respectively. Kinetic and thermodynamic parameters (Ea, H, and S) were calculated for uncoated and coated LCS. An atomic force microscope (AFM) studied the coating surface morphology. Electrochemical impedance spectroscopy (EIS) was used to evaluate the coating resistance.
