摘要：Bisphenol A/diaminodiphenylmethane (BAddm)-based polybenzoxazine precursor was synthesized from 4,4'-diaminodiphenylmethane, bisphenol A, and paraformaldehyde. The curing behavior of BA-ddm was studied by using differential scanning calorimeter and Fourier transform infrared spectrometer techniques. To verify the anticorrosion property, cured polybenzoxazine (PBA-ddm) coatings were prepared on mild steel (MS) through dip-coating and thermal curing methods. The surface properties of cured PBA-ddm coatings were characterized by microscopy and contact angle measurement. The electrochemical measurements were carried out to investigate the corrosion properties of PBA-ddm-coated MS. The results showed that PBA-ddm-coated MS samples exhibited high anticorrosive performance with the corrosion current reduced by two orders of magnitude than that of pristine MS.
