Abstract The photothermal superhydrophobic coating has garnered considerable attention owing to its captivating and promising deicing applications in an eco‐friendly efficient way. However, designing active‐deicing nanocoating with both mechanical stability, superhydrophobicity, performance from molecular structure remains a challenge. Herein, robust epoxy (EP)&polysiloxane (PS) (EP&PS‐PSC) is constructed by combining hydrophilic EP hydrophobic PS along graphene nanosheets via phase separation swelling treatment strategy. Notably, polar lower volume shrinkage can effectively inhibit swelling‐type polymers achieve subsequent micro‐/nanostructures construction. Besides, the also provide strong interaction interactions between micro‐/nanostructures. While non‐polar liquid silicon rubber provides low surface energy for achieving composite Furthermore, as‐prepared EP&PS‐PSC exhibits exceptional stability (e.g., 100 cycled sandpaper linear abrasion g load) WCA of 154.9° ± 1.2° WSA 4.8° 1.3°, which beneficial improve physicochemical performance. combination long‐term superhydrophobicity capability results maximum temperature 59.4 °C being achieved within 400 s under standard sunlight.

Abstract In the quest for advanced coatings suitable foldable electronics and photovoltaic systems, there is a pressing need materials that combine transparency with durability. To address this, innovative special horizontal stripes transparent (SHT) coating prepared by capillary gravity self‐assembly methods. This derived from structural principles of corn bracts created through crosslinking epoxy hydrophobic modified SiO 2 an organosilicon prepolymer, bridged double terminal amino polydimethylsiloxane. The pattern surface makes SHT more than glass, bionic structure proven to be highly durable under extreme temperature fluctuations, withstanding tests 150 −20 °C over 192 h, enduring 30 days ultraviolet radiation exposure at 365 nm intensity W m − . Moreover, even after 3000 cycles scissors abrasion, maintained its anti‐fouling properties mechanical resilience. It also demonstrated remarkable chemical stability across range solvents. can easily applied various flexible rigid substrates using brush, poised find broad applications in realm optical devices.

In the field of smart materials, there is a demand to fabricate surfaces with superhydrophobic and conductive features in cost-effective efficient fabrication manner. this study, high-efficiency approach for fabricating multifunctional presented. By using fiber laser ablating PDMS/CNT nanocomposite surface, (WCA = 157°, SA 7.35°) unidirectional groove structures were fabricated high efficiency 3.5 s/cm2 under spacing 75 μm scanning speed 500 mm/s. Three separate application scenarios are demonstrated. The results showed that facilitated nondestructive droplet transfer enabled fluid manipulation via self-floating. Its load-bearing capacity was increased by 49.8%. movement on water accelerated 116% after irradiation, it achieved optically controllable motion complex paths as light-driven actuators. Notably, they maintained exceptional properties, even when stretched strain 75%. can effectively monitor various underwater signals such finger flexion, wrist fist clenching, which exhibited great potential sensor monitoring.

Ice accumulation and moisture condensation pose significant challenges to the longevity performance of modern architectural materials. Superhydrophobic anti-icing coatings often suffer mechanical chemical degradation, particularly in outdoor settings subject heavy rain or impact. Additionally, most existing are airtight, leading humidity potential substrate deterioration, especially cement-based To address these challenges, we developed a nonfluorinated, breathable superhydrophobic coating by spraying PDMS-IPDI-TFB supramolecular network (PIT) mixed with polydopamine nanoparticles (PDA NPs). The optimized (PSC-40) exhibits high breathability, prevents blistering cracking, demonstrates exceptional durability. Remarkably, it withstands high-speed water jet impacts (We = 16,000) retains superhydrophobicity after damage. also possesses self-healing capabilities via hydrogen bonds dynamic covalent bonds, enabling recovery under sunlight, room temperature, underwater conditions. Its is evident from delayed freezing time (−15 °C) 1610 s significantly reduced ice adhesion strength (32.6 kPa). Under rapidly melts droplets layers within 138 695 s, respectively. This work introduces robust, anti/deicing capabilities, offering scalable solutions for outdoor, concrete-based applications.
