“…Furthermore, among the “mountains”, the growth rate at the “peaks” is the largest compared with the “gullies”, which makes the “elevation” rise rapidly and continuously, eventually forming giant grooves as shown in Figure S3B. Besides, on the “hillsides” where the growth rate is relatively small, the growth of Ni nanocones mainly follows the spiral dislocation growth mechanism, which has been discussed in detail in previous works. , …”

The anisotropic surface prepared by the top-down etching technology shows unique advantages in terms of functional superhydrophobicity. However, it still has a shackle of the smallest etching size, which largely restricts the development of better superhydrophobicity. Therefore, it is still a huge challenge to realize the stepless size adjustment of an anisotropic surface in order to achieve better functionalization. In this work, a bottom-up approach inspired via the modular segmented preparation technology has been used to successfully build an anisotropic, locally ordered functionalized unique superhydrophobic structure, whose contact and rebound time of water droplets is extremely short. Furthermore, this structure with artfully arranged "tracks", which has a relatively large contact angle value, not only lasts more than 15 consecutive bounce cycles in the same direction, where the droplets after merging still bounce, but also exhibits a significant anisotropic sliding behavior, which is presented in different sliding angles, toward droplets rolling in different directions and has lower adhesion work and better self-cleaning and anti-fouling performance. Besides, some mechanisms such as the reduction−replacement−reduction cycle and repulsion−adhesion−switching have been proposed especially in modular preparation and anisotropic sliding behavior. More importantly, this sorted bottom-up structure has great potential for achieving higher efficiency of functionalized superhydrophobicity and other related applications.

“…At the same time, these small cone layers overlap and tend to diffuse to the periphery, which gives these Ni nanocones a unique morphology. These Ni nanocones with special surface textures could be explained by the growth mechanism of multidirections of screw dislocation and the multidimensional growth mechanism of global order and local disorder, which have been discussed in detail in our previous study. , …”

XRD measurement is performed to confirm the phase composition, and the results are displayed in Figure 4f.…”

The development of a unique multilayer detached superhydrophobic structure inspired by biology with excellent superhydrophobic properties, extremely short rebound time, and low surface free energy has become a challenging issue. In this work, a superhydrophobic coating is prepared on the surface of Al 1060 via a fluorine-free, efficient, economical, and environmentfriendly approach. First, a Ni nanocone layer is obtained from a recyclable electrodeposition solution. Then, stearic acid is prepared on the Ni nanocone layer by dip-coating technology, resulting in a special superhydrophobic surface called the "trampoline" structure, which is quite different from the Ni nanocone structure, as the substrate. The contact angle of water is 161.3°, and the sliding angle is 7°. In addition, the superhydrophobic coating with this special structure has had great achievement in adhesion work, resilience performance, porosity, corrosion resistance, and self-cleaning and antifouling performance. So far, very few reports have analyzed the performance of this special structure. To explain the bounce performance induced by this special trampoline structure, a multidimensional superhydrophobic bouncing mechanism was proposed. Furthermore, this work is expected to provide inspiration for future applications of the unique nonfluorinated trampoline structure in superhydrophobic materials.

“…It is believed that the presence of the [Ni(NH 3 ) x ] 2+ complex in the Helmholtz double layer (HDL) of the cathode will tend the Ni 2+ ions to sites, which can easily form cones and with time, these cones become larger. 52 Fig. S2 † shows the CV electrodeposition curve of NiCoMn nanosheets deposited from a bath containing Ni 2+ , Co 2+ , and Mn 2+ .…”
