“…Contrary to the fish scales, if the oil adhesion of a superoleophobic surface is very high rather than ultralow, the oil droplet will be able to stick to the surface no matter the substrate is tilted at any angle. Such high adhesive surface can be used to transport small oil droplet without any volume loss . Because of the important applications in manipulating oil droplets on the target materials, the multifunctional superoleophobic surfaces showing controllable adhesion (from low to high) to oil droplet have attracted growing interest among the researchers …”

“…Inspired by the underwater superoleophobicity of fish scales, various technologies have been developed to fabricate underwater superoleophobic surfaces following the design principle of “from in‐air superhydrophilicity to underwater superoleophobicity,” such as lithography, templating, chemical etching, hydrothermal method, self‐assembly, electrochemical deposition, electrochemical anodization, and spray/dip coating . The same as the superhydrophobic surfaces, the artificial underwater superoleophobic surfaces have also attracted much attention recently owning to their significant applications in antioil coatings, oil/water separation, manipulation of oil microdroplets, self‐cleaning, bioadhesion, antiblocking, guiding the movement of oil droplets, floating on oil, and oil droplets patterning . Underwater superoleophobic surfaces can be successfully prepared by the above‐mentioned traditional methods, but those methods, more or less, have to face their inherent limitations, such as complex fabrication process, tight restriction on special materials, and lack flexibility.…”

The preparation of superhydrophilic/superoleophilic/underwater superoleophobic surfaces is inspired by natural surfaces such as fish scales possessing hierarchical micro/nanostructures.In this paper, we report the assembly of self-organized hierarchical microcones arrays on nickel surface by sucrose solution-assisted femtosecond laser irradiation. The processed surface is superhydrophilic (13.47 o~4 .01 o ), superoleophilic (7.45 o~3 .73 o ), and underwater superoleophobic (135.22 o~1 66.16 o ), which are comparable to that of the fish scales. The wettabilities of the processed surfaces are tunable by adjusting the mass ratio of the sucrose to water and pulse energy to control the height (1.62~10.34 µm) and size (2.1~2.81 µm) of the microcones. Multifunctional liquid manipulation such as microdroplet transferring, static and dynamic storage, liquid transportation and mixing are demonstrated. Our proposed method features rapidness, simplicity and easiness of large-area fabrication, which may find broader applications in many fields such as microfluidic devices, fluid microreactors, biomedicine, biomedical scaffold, and chemical-biological sensors.-3 -preparing underwater superoleophobic surfaces by femtosecond laser microfabrication on Ti materials. As a kind of important ferromagnetic metal, nickel shows outstanding optical, catalytic, electrical, and superior resistant characteristics to corrosion, which makes it widely applicable in electronics, [19] nickel-batteries, [20] alloy, [21] and chemical catalyst. [22] However, the present fabrication on nickel material using femtosecond laser microfabrication and studying the underwater superoleophobicity are still few. Therefore, it is of great interests to produce underwater superoleophobic surfaces on nickel substrates, and study their functions and potential applications.Here, we demonstrate a facile and rapid method to fabricate large-area microcones arrays by one-step femtosecond laser irradiation on nickel targets in sucrose solutions. The prepared surfaces are superhydrophilic in air and superoleophobic in water. It is indicated that the height and size are tunable by controlling the ratio of the sucrose to the water in the solution and the laser pulse energy, leading to controllable wettabilities for water and oil. Furthermore, these processed surfaces covered with microcones arrays exhibit multiple functions, which can be used in microfluidic devices, fluid microreactors, biomedicine, biomedical scaffold, chemical, and biological sensors. Experimental SectionMaterials: Nickel sheets with a purity of 99.99% were purchased from New Metal Material Tech. Co., Ltd., Beijing, China. The oil used in our experiment is 1, 2dichloroethane, and the chemical formula was C 2 H 4 Cl 2 . The sucrose (chemical formula is C 12 H 22 O 11 and the relative molecular mass is 342.3), milk (the color is white) and the red ink are purchased from supermarket. The sucrose solution is prepared by dissolving sucrose with a certain mass into 100g distilled water, and the mass ratio ran...
