To achieve this, the researchers combined reversible disulphide bonds, acylhydrazone bonds and thermo-sensitive hydrogen bonds. This structure significantly enhances the barrier effect, mechanical robustness and self-healing efficiency of the coating. Don’t miss this premier event for professionals focused on corrosion protection in demanding environments like offshore oil rigs, ships, pipelines, and civil engineering projects. High self-healing efficiency and corrosion resistanceThe developed polymer, WPUSS-P4, achieved a yield stress of 14.6 MPa, a tensile strength of 20.9 MPa and a self-healing efficiency of 93 %.
