摘要：

Advanced energy-water systems demand fabrication of high-performance water purification membranes. Poly-meric membranes are typically hydrophobic, not amenable to conventional surface functionalization methods. Mussel adhesive proteins have inspired numerous adhesive polymer coatings via the structure-function simulation. Nonetheless, research about maximizing membrane interface hydrophilization and relevant concept guidance are still far from enough. Here, we put forward a "split-and-adjust" concept and proof it using a simplified catechol/silane biomimetic composite coating system for boosting interface hydrophilization. As a result, the hierarchically nanostructured silicified hydrophilic membranes were fabricated. The hydrophilicity could be tailored via tuning reagent dose recipes. The as-fabricated hydrophilic membrane presented benign fouling resistance in oil-in-water emulsion filtration tests. In addition, the rinsing examination indicates the coating is well stabilized. The as-developed "split-and-adjust" concept for the composite coating system provides promising guidance to broaden and optimize the customized biomimetic interface functionalization toolbox.
