“…The polarization curves in Figure 10 show that the self‐corrosion current densities of both EHPAM and DHPAM solutions at the cathode and anode decreased to a certain extent and increased with increasing concentration compared to the blank hydrochloric acid solution, indicating that both EHPAM and DHPAM are effective corrosion inhibitors for Q235 steel sheets. The anodic self‐corrosion current density of EHPAM and DHPAM decreased more sharply than that of the cathodic self‐corrosion current density, and the change of corrosion potential was not very marked compared with that of the blank hydrochloric acid solution, demonstrating that EHPAM and DHPAM are mixed corrosion inhibitors with anodic inhibition as the main type [56,57] . They play the role of corrosion inhibition by passivating the metal through the migration of anions to the metal anode.…”

Polyacrylamide‐based hydrophobically associating polymers (HAPAM) containing capsaicin derivatives and itaconic acid with acrylamide (AM) and methacrylic acid (MAA) as the main bodies, and N‐vinylpyrrolidone (NVP) as the functional monomer are prepared by a one‐pot synthesis of the soap‐free emulsion polymerization process. The structure is characterized by fourier transform infrared (FTIR) and 1H nuclear magnetic resonance (1H NMR), and thermal gravimetric analyzer (TGA) explores thermal stability. For achieving proper purification, excellent preservation and convenient transportation of the polymer and to advance its practical engineering applications, two different treatments, namely ethanol washout and freeze‐drying, are carried out and compared. The surface morphology observation manifests that the freeze‐drying products (DHPAM) better protect the three‐dimensional cross‐linked network structure formed by various supramolecular forces such as hydrophobic association, electrostatic and hydrogen bonding inside the polymer than the ethanol washout products (EHPAM), which well explains why DHPAM has lower critical association concentration (CAC), greater resistance to high temperature and high salt, and better corrosion inhibition performance than EHPAM. It is significant for strengthening the application of polymers in related fields, especially oil and gas extraction.

Scale inhibitors are effective in preventing CaCO 3 scaling in geothermal systems, but the scale inhibition performance and price of commercial scale inhibitors in high-temperature and high-salinity water are still not ideal. In this work, a novel modified carboxymethylated β-cyclodextrin tetrameric (CAAS) scale inhibitor was synthesized using carboxymethylated β-cyclodextrin, acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid (AMPS), and p-styrenesulfonate (SSS) by free radical polymerization, and deprotonated CAAS (D-CAAS) was prepared based on CAAS. The results of the static test showed that the CaCO 3 scale inhibition efficiency of D-CAAS reached 90.8% at 100 C and 800 mg/L Ca 2+ . Compared with that of previous commercial scale inhibitors, the scale inhibition efficiency of D-CAAS was increased by 13.5%, and the price can be decreased by 26.1%. The results of SEM, XRD and molecular dynamics (MD) simulation showed that at 100 C-120 C, the deprotonation of D-CAAS enhanced the weak interaction between D-CAAS and CaCO 3 , inducing the transformation between calcite and vaterite and forming a loose scale. Deprotonation weakens the hydrogen bond between D-CAAS and water to reduce the energy required for the binding of D-CAAS to the surface of CaCO 3 . This study is expected to provide a low-cost and high-efficiency CaCO 3 scale inhibitor for geothermal applications.
