Insights into the hydrophobic coating with integrated high-efficiency anti-corrosion, anti-biofouling and self-healing properties based on anti-bacterial nano LDH materials
CORROSION SCIENCE(2024)
Abstract
In this work, a series of hydrophobic coatings based on the anti-bacterial nano-hydrotalcite (LDH) materials were successfully prepared in this work. Results indicate that the introduction of Ag and sodium pyrithione (SPT) can effectively increase the anti-bacterial performance of NiAlZn LDH. The designed Ag/NiAlZn LDH and Ag/NiAlZn LDH-SPT coatings not only possess high anti-corrosion performance but can effectively inhibit the adhesion of Pseudomonas aeruginosa and Chlorella vulgaris . The anti-biofouling efficiencies of Ag/NiAlZn LDH-SPT coating against P. aeruginosa and C. vulgaris are 98.5% and 98.2%. Ag/NiAlZn LDH-SPT coating possesses integrated high-efficiency anti-corrosion, anti-biofouling and self-healing properties and good mechanical performance.
