Nepenthes mirabilis-inspired slippery liquid-infused porous surface (SLIPS) with intrinsically smooth in molecular scale has obvious advantages such as omnophobicity, self-healing property, pressure stability and enhanced optical transparency. This bio-inspired material exhibits broad application prospects in antifouling, liquid- and ice-repellent coatings, self-cleaning as well as oil-water separation fields. In this project, we aim at constructing a novel magnetic-responsive material with multiple self-healing and super slippery performances. The research will focus on revealing the forming mechanism of this novel biomimetic SLIPS material. The mechanism of multiple self-healing properties and the special surface physicochemical character will be systematic studied. By introducing the surface-modified nanoparticles (SiO2/Fe3O4) into functionalized fluorinated copolymers, the fluorinated nanocomposite copolymers will be obtained via in situ polymerization with acrylates containing disulfide bonds as cross-linking agent. Then the cross-linked nanocomposite will be infused with various kinds of lubricants, and SLIPS materials with long-term stability can be prepared. We will investigate the omniphobicity, anti-adhesive and self-cleaning properties of SLIPS and reveal the mechanism for the formation and super slippery of SLIPS surface. The smart response and multiple self-healing properties of the SLIPS should be achieved because of the magnetic-responsive property of Fe3O4 nanoparticles and the translocation exchange reaction of disulfide bonds. On the basis of these studies, the application of SLIPS material will be expanded in marine coating, anti-icing, and chemical heat transfer aspects. Our investigation will provide theoretical foundation for preparing advanced super wetting materials through biomimetic methods.
