Omniphobic coatings which can efficiently diminish the interfacial reactions between the underlying substrates and foreign liquids present broad technological impacts and enormous potential applications, whereas the current prepared superamphiphobic surfaces are constrained to their weak robustness owing to the vulnerability of the sophisticated hierarchical structures. Herein, we employed oxidative polymerization method to graft polyaniline (PANI) nanofibers on arbitrarily shaped surfaces that further modified with perfluoroalkylthiol and infiltrated with perfluoropolyether lubricant, constructing a slippery lubricant-infused porous surfaces (SLIPS). With the enlargement of the polymerization time, the coverage degree of PANI coating on the glass surface gradually increased and their transmittance reduced simultaneously. Meanwhile, the influences of the structure geometry and surface chemistry on the slippery behavior of foreign liquids on the SLIPS were investigated, further verifying that the synergetic effect of the adequate texture roughness and matched surface chemistry is the prerequisite for preparing steady and defect-free lubricant layer. Moreover, the prepared SLIPS could be applied in various promising applications such as anti-fogging, anti-fingerprint, three-dimensional droplet manipulation and crude-oil lossless transportation. More importantly, the lubricant layer remained stable on the surfaces after long-term storage in high/low temperature, water immersion and ultraviolet irradiation, and displayed superior mechanical resistance to water impact, sandpaper abrasions and knife scratches. Therefore, this strategy for fabricating nepenthes-inspired lubricant-infused surfaces is expected to further promote the cognition and manufacture of multifunctional omniphobic materials.

仿生滑滑润滑剂注入透明和多功能全疏水表面的轻松制造

可以有效减少底层基材与外来液体之间的界面反应的全疏水涂层具有广泛的技术影响和巨大的潜在应用，而目前制备的超疏水表面由于复杂的分层结构的脆弱性而受限于其弱的鲁棒性。在此，我们采用氧化聚合方法将聚苯胺（PANI）纳米纤维接枝在任意形状的表面上，该表面用全氟烷基硫醇进一步改性并用全氟聚醚润滑剂渗透，构建了光滑的润滑剂注入多孔表面（SLIPS）。随着聚合时间的增加，PANI涂层在玻璃表面的覆盖度逐渐增加，同时透光率降低。同时，研究了结构几何形状和表面化学对 SLIPS 上外来液体滑动行为的影响，进一步验证了足够的纹理粗糙度和匹配的表面化学的协同作用是制备稳定和无缺陷的润滑层的先决条件。此外，所制备的SLIPS可用于防雾、防指纹、三维液滴操纵和原油无损输送等各种有前景的应用。更重要的是，润滑层在高低温、浸水和紫外线照射下长期储存后表面保持稳定，并显示出优异的抗水冲击、砂纸磨损和刀划痕的机械性能。所以，
