What's Happening?
A research team from China has developed a novel self-healing coating based on waterborne polyurethane (WPU) aimed at improving mechanical strength, self-healing performance, and anti-corrosion capacity. The coating utilizes reversible disulphide bonds, acylhydrazone bonds, and thermo-sensitive hydrogen bonds to create dual dynamic networks through chemical cross-linking and physical hydrogen bonding. This innovative structure significantly enhances the barrier effect, mechanical robustness, and self-healing efficiency of the coating. The polymer, WPUSS-P4, demonstrated impressive results in corrosion tests, maintaining strong protection after extensive exposure to salt solutions. The research suggests a promising strategy for sustainable and environmentally friendly anti-corrosion materials suitable for metallic substrates.
