A novel polyurea containing oligoaniline pendants (PU-p-OA) was synthesized by one-step synthetic route. The molecular structure of PU-p-OA was confirmed by Fourier transform infrared spectra (FTIR), nuclear magnetic resonance (NMR), and gel permeation chromatography (GPC), and its thermal stability was probed via thermal gravimetric analysis (TGA). Due to the introduction of the oligoaniline segments, PU-p-OA showed expected spectroscopic properties and reversible electroactivity. The electrochromic behavior of a PU-p-OA/ITO electrode was investigated by spectrochronoamperometry in detail, exhibiting good electrochromic properties with high contrast value. Moreover, the inhibition effect of the electroactive PU-p-OA coatings on the cold rolled steel (CRS) in 5 wt% sodium chloride solution was investigated by Tafel plot analysis and electrochemical impedance spectroscopy. Furthermore, comparative anticorrosive study among PU-p-OA, normal polyurea (NPU), parent aniline tetramer (PAT), and NPU/PAT blend was accomplished, which indicated that the obtained PU-p-OA was a good corrosion inhibitor for CRS in brine medium.

“…Our preliminary studies also confirmed that the effects of the MF had a positive correlation with orientation and stretching, doping ratio, crystallinity and thermal stability of the polyaniline (PANI) and the reaction rate of aniline polymerization. [1][2][3] As one of the most promising commercial conductive polymers, PANI has been widely used in basic materials, such as pH-sensors, 4 biosensors, 5 rechargeable batteries, 6,7 membranes, 8 electrochromic displays 9 and corrosion-protecting coating. 10 However, the basic research of electrochemical properties of the PANI has been seriously limited due to its relatively poor solubility and fusibility.…”

A new, convenient and economical method was established firstly, which took loaded polyaniline (PANI) carbon paper as the working electrode to real-time characterize and analyze the electrochemical properties of the PANI synthesized by emulsion polymerization in constant magnetic field (MF, 0.4 T). The characterization results of the electrochemical properties of the PANI had been proved by contrast analysis of the thermal stability of conductivity, FT-IR, XRD and TGA of the PANI. The experimental results of cyclic voltammogram, AC impedance, Tafel curve and electrochemical stability showed that the PANI synthesized in the presence of the MF had larger redox current, smaller charge resistance, higher corrosion potential and better electrochemical stability. The PANI thermal stability of conductivity had been measured in the temperature range from 20 to 140 , and the results showed that the ℃ PANI synthesized in the presence of the MF had better thermal stability of conductivity. The results of FT-IR, XRD and TGA indicated that the characteristic peaks of FT-IR spectra of the PANI synthesized in the presence of the MF shifted to the lower wavenumbers, and its crystallinity and thermal stability were also improved.
