What are the necessary requirements in polymers to show anticorrosive properties?
Answers
Explanation:
The conducting polymer polyaniline–amino trimethylene phosphonic acid (PANI–ATMP) was prepared by chemical oxidative method using
ammonium persulphate. The polymer was characterized by FTIR, UV and X-ray fluorescence spectroscopy and XRD. The conductivity of the
polymer was measured by four probe resistivity meter. The polymer was dispersed in epoxy resin and the corrosion protection property of
the coating for steel has been evaluated by salt spray, open circuit potential measurements and EIS. It has been found that the open circuit
potentials of coated steel have been shifted to noble direction after the initial shift in the active direction in 3% NaCl. Besides, the charge transfer
resistance values have been found to increase with time due to passivation of steel by PANI–ATMP pigment, indicating the protective nature of the
coating.
