Freshwater scarcity is a pressing global issue, and water collection from fog offers promising, cost-effective, environmentally friendly solution. Inspired by the mechanisms of desert beetles, spider webs, cactus spines, we designed interconnecting superhydrophilic-superhydrophobic-region patterns for efficient collection, which was achieved low-energy fluorine-containing coating on Aluminum (Al) substrate followed laser marker ablation to form superhydrophilic pattern out overall superhydrophobic surface.

Using superhydrophobic surfaces (SHSs) with the water-repellent Cassie–Baxter (CB) state is widely acknowledged as an effective approach for anti-icing performances. Nonetheless, CB susceptible to diverse physical phenomena (e.g., vapor condensation, gas contraction, etc.) at low temperatures, resulting in transition sticky Wenzel and loss of capabilities. SHSs various micronanostructures have been empirically examined enhancing stability; however, energy barrier transits from metastable stable thus stability enhancement currently not enough guarantee a well appliable performance temperatures. Here, we proposed dual-energy-barrier design strategy on micronanostructures. Rather than typical single conventional CB-to-Wenzel transition, introduced two states (i.e., I II), where needed go through II then state, significantly improving entire stability. We applied ultrafast laser fabricate this micronanostructures, established theoretical framework, performed series experiments. The performances were exhibited long delay icing times (over 27,000 s) ice-adhesion strengths (0.9 kPa). kinetic mechanism underpinning enhanced was elucidated attributed preferential liquid pinning shallow closed structures, enabling higher CB-Wenzel sustain state. Comprehensive durability tests further corroborated potentials designed structures applications.

Spontaneous and directional water droplet transportation based on patterned surface with super-wettability is crucial for the development of frontier science technology. However, cannot meet both long distance fast simultaneously. Here, we overcame this limitation by proposing an asymmetric serial brachistochrone-shaped pattern (ASBP). Water could be transported ASBP a 72.52 mm velocity 158 mm/s after series single-factor experiments, orthogonal design optimization, junction transition optimization. In addition, curved ASBP, super-long multi-droplet scenarios, at inclination angle. Moreover, acidic alkaline aqueous solution showed similar ASBP. Based aforementioned superb capacity, can applied in fields fog collection, mixing reaction, reagent detection. This work has strong implications promoting application field high-performance fluid systems.

Abstract Superhydrophobic surfaces have broad application prospects in various fields due to their special surface wettability. However, most artificial superhydrophobic are fabricated on rigid substrates or flexible with low deformability, and performance is difficult guarantee when a large deformation occurs, hindering further application. Here, ultra‐stretchable (SU) film by simple template replication energy modification method using the mixture of vulcanized natural latex (VNR) silicone emulsion as raw material. The prepared SU exhibits excellent elasticity wettability stability can maintain good superhydrophobicity even after 500% tensile strain. Moreover, droplets dropped bounced time without any residue, avoiding accumulation film. Finally, magnetoelectric generator composed an electromagnetic system developed realize efficient utilization conversion droplet via impacting bouncing behavior.
