Corrosion protection of mild steel surfaces
These networks were prepared by blending conducting polyanilines with isocyanate-containing prepolyurethanes.
PU-PANI shows best protection
Free-standing polyurethane films were obtained after a moisture cure for several days to ensure complete reaction of the excess isocyanate. The films were electrochemically active with conductivity in the range of 10−2 to 10−3 S/cm. The solution blends and formed films were characterised by infrared, ultraviolet, thermogravimetric analysis, and differential scanning calorimetry. Electrochemical corrosion studies showed excellent corrosion protection in the following order: PU-PANI PU-PmAP PU-PoA.
The study is published in: Journal of Applied Polymer Science, Volume 135, Issue 6, February 10, 2018.
The book Corrosion Protection brings together all the disciplines involved in the creation and use of protective coatings for metals. It presents the latest insights into the quality and chemistry of surfaces, the proper way to prepare them by conversion treatment, the function of resins and anticorrosion pigments in paints, and novel concepts in corrosion protection
