Catechol (CA) was used as a hydrophilic backbone, 3\u2010aminopropyltriethoxysilane (KH550) as a cross\u2010linker, sodium periodate (SP) as an oxidation accelerator and Fe\n                    <jats:sup>3+<\/jats:sup>\n                    as a chelation enhancer to achieve hydrophilic modification of the PVDF membrane through synergistic oxidative cross\u2010linking and metal chelation. The modified membrane exhibits a uniform micro\u2011nanoparticle surface structure, imparting superhydrophilicity (water contact angle \u2248 0\u00b0) and underwater superoleophobicity (oil contact angle up to 160\u00b0). It demonstrates excellent separation performance, with a permeation flux of 25\u00a0902 L\u00b7m\n                    <jats:sup>\u22122<\/jats:sup>\n                    \u00b7h\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00b7bar\n                    <jats:sup>\u22121<\/jats:sup>\n                    and an oil rejection rate of 99.37% for oil\u2010in\u2010water emulsions. The key innovation lies in the synergistic oxidation\u2013chelation mechanism, allowing for rapid film formation while ensuring robust interfacial adhesion. After 180 days of immersion in acidic, alkaline, and saline environments, the membrane retained its structural integrity and underwater anti\u2010oil performance, effectively overcoming the long\u2010standing issue of coating delamination in complex media.
