Enhanced anticorrosion properties of composite coatings containing polyvinyl butyral and polyaniline-carbonized polyaniline

A g‐C3N4/PANI S‐scheme heterojunction with face‐to‐face structure to improve the anticorrosion property on Q235 steel and enhanced mechanism study

“…13,14,16 Besides, the PANI coating layer is the most suitable substrate layer due to the electron conductivity and the density structure; the density structure can suppress the electrons migrated from substrate on surface layers and the electron conductivity can transfer the electron (generated from photocatalytic coating layers) from surface layer to substrate to suppress the corrosion of metals. [17][18][19][20] Furthermore, the protonation of PANI electronically conductive is widely employed in the corrosion protection fields and promotes the passivation layer formation on the metal surface, maintaining the redox potential of substrate to further protect the substrate metals. 21,22 Graphitic carbon nitride (g-C 3 N 4 ) has been extensively used in various fields including solar cell, fuel cell, piezoelectricity, photoelectrochemical devices, energy storage and transfer, light-emitting diodes, environmental pollution purification, and anticorrosion coatings because of the low cost, excellent biocompatibility, stable chemical property, corrosion resistance, tunable, and outstanding electronic performances.…”

P/N Junction TiO2 Nanotube-Polyaniline Molecular Imprinting Photoelectrochemistry Micro-Sensor with a Self-Elution Function Can Efficiently Detect Chloramphenicol

“…Because the molecular structure of CAP has two hydroxyl groups, an amide bond, and a nitro group, they may form intermolecular hydrogen bonds with the amine group to facilitate CAP recognition . The molecular chain of polyaniline (PANI) has a P-electron conjugated structure, so it can be widely used in supercapacitors, magnetic shielding, , corrosion prevention, and many other fields . Moreover, photo-electrochemistry (PEC) has attracted people’s attention because the photoelectric materials spontaneously produce current after illumination by light with no extra energy consumed. − Compared to the problems of general elution in MIPs, the PEC technology used in elution can shorten the process and improve the elution efficiency and detection sensitivity.…”
