“…The impedance modulus of PAMBSP1 was 6.28 × 10 5 Ω·cm 2 and increased to 1.46 × 10 7 Ω·cm 2 and 3.08 × 10 6 Ω·cm 2 for PAMBSP2 and PAMBSP3, respectively. The impedance modulus of PAMBSP2 coating was one or two order of magnitude higher than that of the other coatings, which illustrating a better corrosion‐resistance of PAMBSP2 coatings 23 . The phosphate group in the PAMBSP coatings could form a protective coating on the surface of the steel panels, isolate the steel surface and air, and then slow down the oxidation rate of the metal surface more efficiently.…”

Novel polymeric surfactant (MBSP) is obtained with phosphate esters monomer (PEGMAP) as the functional monomer in the presence of other acrylic monomers. The synthesized MBSP is further used as emulsifier for preparing the corrosion-resistance polyacrylate coatings (PAMBSP). Attenuated total reflection Fourier transform infrared (ATR-FTIR) and nuclear magnetic resonance results show that phosphate esters functional monomer was introduced into the MBSP molecular chains. The surface tension measurements illustrated that with the PEGMAP content 1%, the lowest surface tension 44.45 mN/m and the equilibrium concentration critical micellar concentration (CMC) 1.02 g/L of MBSP are obtained. The stability analysis of the PAMBSP emulsions demonstrates that the Turbiscan Stability Index (TSI) value decreased from 0.64 to 0.32 with the PEGMAP content increased from 1% to 3%. The electrochemical analysis displays that with PEGMAP content 3%, the biggest corrosion potential À0.02 V, smallest etching current density 2.19 Â 10 À9 A•cm 2 and biggest impedance modulus 1.46 Â 10 7 ΩÁcm 2 was obtained.

“…Different contrasts were also observed in TEM micrographs of core-shell self-assembled particles formed by CPs and insulating polymers, as for example those involving polyaniline and polyacrylates. 47 However, in that particular case, the CP was located in the shell instead of the core. Rod-coil structures were also carefully observed by TEM, with further experiments carried out with very low concentration of the new copolymer in acetone solution (0.004 mg/mL).…”

“…It was favorable to dissolve PANDB in common organic solvents. Thus, the PANDB-based materials have appropriate applications such as antistatic materials [ 9 , 10 , 11 , 12 , 13 ], electrostatic discharge, electromagnetic interference (EMI) shielding materials, anticorrosion coatings [ 14 , 15 , 16 ], batteries [ 17 ], sensors [ 18 ], etc.…”

Conductive Polyaniline Doped with Dodecyl Benzene Sulfonic Acid: Synthesis, Characterization, and Antistatic Application

A novel method was conducted to synthesize conductive polyaniline (PANI) doped with dodecyl benzene sulfonic acid (DBSA) (PANDB) in xylene by using chemical oxidative polymerization at 25 °C. Meanwhile, the synthesis process was photographed. Results showed as the reaction time was increased, and the color of the product was gradually turned into dark green. The influence of different synthesis time on properties of synthesized PANDB was then examined by a Fourier transform infrared (FTIR) spectrometer, an ultraviolet-visible spectrophotometer (UV-vis), a four-point measurement method, and a Field-emittance scanning electron microscope (FE-SEM). The result indicated that the optimum reaction time was 24 h with conductivity at around 2.03 S/cm. FE-SEM images and the conductivity testing showed that the more needle-like shapes in resulted PANDB, the higher the conductivity. The synthesized PANDB solution was blended with UV curable coating firstly and then coated on polyethylene terephthalate (PET) sheet. The UV coating/PANDB conductive composite films displayed an impressive translucency along with an adequate flexibility at room temperature. The UV coating/PANDB conductive composite film on PET sheet was flexible, transparent, and with antistatic function.
