One-step plant-inspired reaction that transform membrane hydrophobicity into high hydrophilicity and underwater super oleophobicity for oil-in-water emulsion separation

Here we report a universal and cost-effective strategy via a one-step levodopa (l-DOPA)/3-amino-propyltriethoxysilane (APTES) reaction modified hydrophobic membrane for highly efficient separation of oil-water emulsions. Interestingly, the newly designed composite membrane possesses both high hydrophilicity and underwater super oleophobicity. Under gravity-driven separation conditions, the membrane displays superior efficiency to separate...
