Biomimetic Multi‑Responsive Superwettable Materials for Oil–Water Separation (IMAGE)
Caption
- By integrating Young's equation, the Wenzel model, and the Cassie–Baxter model, the critical influence of biomimetic micro-/nano-structures and surface chemical regulation on achieving superwettability and smart switching is revealed, providing a theoretical foundation for the design of high-performance separation materials.
- In analyzing stimulus-responsive catalytic cleaning membranes, the four-level synergistic coupling mechanism between the physical barrier effect of the surface hydration layer and the degradative action of catalytically generated reactive oxygen species is elucidated, offering theoretical support for achieving long-term antifouling performance and integrated separation degradation functionality.
- The response principles and oil-water separation performance of temperature, pH, photo, electric, gas, ion, solvent, and multi-responsive materials are systematically reviewed and comparatively analyzed. Notably, a comprehensive evaluation framework is established through comparative tables across multiple dimensions, such as response speed, regulation precision, reversibility, and energy consumption, thereby providing an intuitive reference for material selection.
