| description | •Phytic acid was used to modify hydrotalcite films by adsorption or ion exchange way.•The corrosion resistance of hydrotalcite films is improved by modification using phytic acid.•Phytic acid modification provides a self-healing effect to hydrotalcite film.
An environmentally friendly corrosion inhibitor phytic acid (PA) has been successfully added to modify the hydrotalcite (HT) film by adsorption and ion exchange approaches. In alkali PA solution, PO43- cannot substitute CO32- in the HT, but adsorb to the external surface; H2PO4-/HPO42- can insert into the HT after decarbonation under acidic condition. Partial decomposition occurs under both conditions. The PA/pH 11-HT film shows superior stability and lasting protective efficiency, and also can provide self-healing effect associated with the P adsorption in the filament. The worse resistance of the PA/pH 6.5-HT film may be related to the micro-cracks. |
