Abstract Water is the source of life and civilization, but water icing causes catastrophic damage to human diverse industrial processes. Currently, superhydrophobic surfaces (inspired by lotus effect) aided anti‐icing attracts intensive attention due their energy‐free property. Here, recent advances in design functionalization are reviewed. The mechanisms advantages conventional, macrostructured, photothermal introduced turn. Conventional surfaces, as well macrostructured ones, easily lose icephobic property under extreme conditions, while strongly rely on solar illumination. To address above issues, a potentially smart strategy found developing storage (MPSS) which integrate functions materials, phase change materials (PCMs), expected achieve all‐day various fields. Finally, latest achievements MPSS showcasing immense potential, highlighted. Besides, perspectives future development provided problems that need be solved practical applications proposed.

Droplet impacting on the film has been an important research topic, which is relevant to many industries and of high utilization value. The droplet process shows excellent mass heat transfer capability, whereas liquid often in a flowing state, morphological deformation energy conversion successive droplets moving were investigated. A three-dimensional volume fluid model coupled with level-set function was established investigate single impact film. asymmetry dynamic dissipation evolution simultaneous processes under different Weber numbers Wed Reynolds Ref thoroughly With smaller larger Ref, sheet downstream crown more suppressed significant. When constant, dimensionless radius related Wed0.2 also power time, exponents differing between upstream downstream. relationship number discussed, kinetic Ek reduction accounts for major part even though surface Es increases due formation crown. Additionally, sheets merging inner outer crowns continuous observed. lower impingement frequency, earlier.

Snow and ice accumulation on surfaces presents significant safety efficiency challenges across various industries, necessitating the development of effective mitigation strategies. In this study, dynamics energy dissipation natural snowflakes impacting superhydrophobic (SHS) were explored using high-speed imaging a novel image processing method. The size, velocity (impact bounce), contact time wet quantitatively analyzed, identifying two primary impact outcomes: bouncing fragmentation. analysis focused to study coefficient restitution (COR) snowflakes. It was found that small (<1.40 mm in diameter) with low velocities (<2.90 m/s) tend be bounced, whereas larger, faster are more likely fragmented. For first time, SHS also reported, introducing dimensionless (DCT) for quantifying during impact. results indicate has cubic relationship snowflake size quadratic its velocity, demonstrating larger dissipate energy. is observed reduction DCT leads an exponential increase COR decrease normalized dissipation, supporting theoretical prediction approaches one zero as zero. These enhancing design anti-icing surfaces, contributing models simulate snow behaviors inform better both active passive

Abstract Liquid leakage of pipeline networks not only results in considerable resource wastage but also leads to environmental pollution and ecological imbalance. In response this global issue, a bioinspired superhydrophobic thermoplastic polyurethane/carbon nanotubes/graphene nanosheets flexible strain sensor (TCGS) has been developed using combination micro-extrusion compression molding surface modification for real-time wireless detection liquid leakage. The TCGS utilizes the synergistic effects Archimedean spiral crack arrays micropores, which are inspired by remarkable sensory capabilities scorpions. This design achieves sensitivity 218.13 at 2%, is an increase 4300%. Additionally, it demonstrates exceptional durability withstanding over 5000 usage cycles. robust superhydrophobicity significantly enhances stability detecting small-scale leakage, enabling precise monitoring across wide range sizes, velocities, compositions while issuing prompt alerts. provides critical early warnings both industrial pipelines potential scenarios everyday life. development utilization ultrasensitive sensors offer innovative effective solution
