The separation of high-viscosity oil-water emulsions remains a global challenge due to ultra-stable interfaces and severe membrane fouling. In this paper, SiO2 micro-nanoparticles coated with polyethyleneimine (PEI) were initially loaded onto stainless steel substrate. This dual-functional design simultaneously modifies surface roughness wettability. Furthermore, covalent crosslinking network was created through the Schiff base reaction between PEI glutaraldehyde (GA) enhance stability membrane. exhibits extreme wettability, superhydrophilicity (WCA = 0°), underwater superoleophobicity (UWOCA 156.9°), enabling gravity-driven pump oil 99.9% efficiency flux 1006 L·m-2·h-1. Moreover, molecular dynamics (MD) simulations demonstrate that SiO2-PEI-GA-modified promotes formation stable hydration layer, reduces oil-layer interaction energy by 85.54%, superior oleophobicity compared unmodified SSM. Efficiency is maintained at 99.8% after 10 cycles. study provides scalable strategy combines hydrophilic particle modification, effectively addressing trade-off performance longevity in treatment viscous emulsions.

Effective elimination of insoluble emulsified oils and soluble organic dyes has received extensively attention in wastewater treatment. In this work, a chitosan polydopamine @ aramid nanofibers (CS&PDA@ANFs) aerogel membrane was fabricated through an integration methodology consisting phase inversion successive deposition PDA CS. The as-prepared possessed satisfactory three-dimensional interpenetrating network architecture with high porosity desirable mechanical property. Furthermore, due to the synergistic effect hydrophilic CS PDA, resultant exhibited good superhydrophilicity underwater superoleophobicity associated favorable oil resistance/antioil fouling properties. combination interconnected porous structures super wettability endowed membranes oil-in-water emulsion separation performance. Particularly, extremely permeation flux (3729 L/m

Abstract 3D superwetting materials struggle to maintain high‐flux steady‐state demulsification for oil‐in‐water emulsions because the accumulated oil within material is difficult discharge rapidly. The water flow shear force can swiftly remove from anti‐fouling surface. In this study, by introducing nanofibers and carbon nanotubes chemical modification, a superhydrophilic‐oleophobic copper foam with pores of several micrometers prepared, which achieve continuous process flux over 57000 L m −2 h −1 rapid hydraulic‐driven release under an additional pressure 5 kPa. Thanks ultra‐small foam, efficiency be still maintained at 97.5%. During process, accumulation surfactants low levels, achieving dynamic equilibrium. With aid second‐stage superhydrophilic mesh, demulsified oil‐water mixtures rapidly separated. This high‐flux, steady‐state, efficient shows great potential industrial applications.
