Published: Nov. 7, 2024

Photothermal superhydrophobic coatings are supposed promising to prevent ice accumulation on infrastructures but often experience significant performance degradation in real icing conditions and lack mechanical robustness. Here, we report design of robust photothermal with three-tier hierarchical micro-/nano-/nanostructures by deposition nanosized MOFs natural attapulgite nanorods, fluorination, controlled phase separation a hydrophobic adhesive spraying assembly. Phase degree content significantly influence the coatings' properties regulating structural parameters morphology. In simulated/real environments, simultaneously show (i) high superhydrophobicity stable Cassie-Baxter states due their low-surface-energy, micro-/nano-/nanostructure, (ii) excellent effect primarily MOFs, (iii) good robustness phase-separated adhesive, reinforcement self-similar structure. Accordingly, combined low thermal conductivity, exhibit remarkable anti-icing/frosting (e.g., no freezing at least 150 min almost free frost 25 min) de-icing/frosting performances fast de-icing 12.7 de-frosting 16.7 such environments.

Bio‐Inspired Hybrid Laser Direct Writing of Interfacial Adhesion for Universal Functional Coatings

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 9, 2024

Abstract Enhancing interfacial adhesion between functional coatings and target surfaces facilitates long‐term stable service by mitigating interferences of mechanical mismatches. Design interlocks affords an effective strategy to strengthen the bonding with durability compatibility, but in‐depth investigations are still lacked. Herein, a gecko‐inspired hierarchical realized hybrid laser direct writing is proposed, which incorporates armored frame scale for surface protection riveted anchor interlocks. Such dual‐scale configurations endow stronger targets than pristine mono‐scale cases, resulting in 2 orders magnitude enhancement resistant tape peeling tests. Utilizing this scheme, laser‐induced integrated deicing system situ manufactured on thermoplastics, primarily comprising superhydrophobic structures, carbon‐based sensors as well adhesive copper (Cu) interconnects heaters, where Cu‐based devices exhibit superior resistance water impacts stress fatigue. Interfacing signal processing modules, such all‐in‐one demonstrates real‐time temperature monitoring high efficiency (4.24 folds faster control group). The facile route intensified holds promise interfaces within advanced equipment under harsh scenarios.

Empowering Photovoltaic Panel Anti-Icing: Superhydrophobic Organic Composite Coating with In Situ Photothermal and Transparency

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(24), P. 31567 - 31575

Published: June 5, 2024

Solar energy is widely used in photovoltaic power generation as a kind of clean energy. However, the liquid film, frosting, and icing on module seriously limit efficiency generation. We developed composite coating (Y6-NanoSH) by combining an situ photothermal transparent Y6 organic film with nanosuperhydrophobic material. The Y6-NanoSH coated glass exhibited excellent optical clarity both indoors outdoors, indicating that holds great promise anti-icing applications for panels. absorbs very little visible light but instead near-infrared region, thereby emitting heat. When exposed to sunlight, panel raises its surface temperature, inhibiting growth accumulation ice frost surface. This achieved through combination emission superhydrophobic repellency, which promotes evaporation rolling away water droplets. validates our success developing photothermal, transparent, capabilities, suitable use panels, well potential car windscreens, transmission lines, curtain walls, weather radomes.

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.
