摘要

Polymer-glass matrix composite exhibits excellent performance as scale inhibitors and anticorrosive coatings. Polysulphanilic acid borate glass composites were chemically performed using potassium dichromate (PDC) as an oxidant in an acidic medium at room temperature. The prepared polymer composites are characterized by IR spectroscopy, XRD and SEM. The interaction between polymer and borate glass is mainly via H-bonding and electrostatic attraction. The efficiency of all the synthesized polymeric samples as anticorrosive coating on mild steel in acidic medium was performed using electrochemical techniques and well compared. The polarization and impedance results confirmed that the composite containing glass borate with 0% CuO (GR100) represented the best coat with an efficiency of 94.6%. The inhibition efficiency of GR100 was decreased to 69% after 7 days of immersion in 1.0 M HCl, and the morphology of the coated samples after 7 days of immersion showed homogenous surface but amorphous surface with pores was observed for the uncoated sample.
