Abstract Ice accretion causes significant energy losses and safety risks across various sectors. Recent research shows that liquid‐like surfaces (LLS) with ice‐shedding properties can be created by covalently attaching linear polymer chains onto smooth substrates sufficient hydroxyl group densities. To expand the substrate scope for LLS, a novel system using non‐halogenated organosilanes attached to commercial epoxy‐silicon ( EpSi ) coating is proposed. The layer, easily applied simple methods, serves as intermediate layer R = 0.94 nm q 0.76 nm). Air plasma activation increases density on , enabling LLS formation via immersion in an organosilane solution. resulting exhibits low contact angle hysteresis (<10°), sliding (SA < 14°), ice adhesion strength τ 20 kPa). Effective generated regardless of type, thickness, or application method. retains its slippery after exposure harsh conditions, including icing/deicing cycles, organic solvents, acidic environment. It also highly transparent T ave 84.5%, t 500 µm) self‐cleaning anti‐staining capabilities. This methodology broadens offering sustainable solution challenges.

Anti-icing gels inhibit ice formation and accretion; however, current iterations face prevalent drawbacks such as poor strength, weak substrate adhesion, limited anti-icing properties. Herein, we propose a novel approach to address these challenges by developing thermomechanical robust polyionic elastomer (PIE) with enhanced The PIE surface exhibits an icing delay time up 5400 s remains frost-free after exposure -10 °C for 3.5 h, attributed the inhibitory effect on ions from ILs polyelectrolyte network. Moreover, remarkable durability, adhesion strengths below 35 kPa undergoing 30 icing/deicing cycle tests at -20 °C. Following sandpaper abrasion (300 cycles), scratching, heat treatment (100 °C, 16 h), strength ca. 20 kPa, highlighting its resilience under various thermal mechanical conditions. This exceptional durability is low volatility of IL ionic interactions within Furthermore, demonstrates favorable self-healing properties strong in both low-temperature ambient environments, facilitated abundance hydrogen bonds electrostatic forces PIE. work presents innovative high-performance, durable, materials potential implications across fields.

In this study, we present the development of advanced anticorrosive icephobic coatings tailored for AA2024-T3 surfaces. These were engineered using polyurethane, incorporating fluoropolyol and isocyanate modified with hydroxyl-terminated silicone oil fluoroalkyl polyhedral oligomeric silsesquioxane (F-POSS) particles. Surface characterization involved contact angle sliding measurements, as well atomic force microscopy. The efficacy was evaluated through a battery tests including differential scanning calorimetry, delay freezing time measurement, impact non-impact ice adhesion measurement (push-off centrifuge), accretion method. Electrochemical impedance spectroscopy served to evaluate anticorrosion performance coatings. integration F-POSS led notable improvements in angles, increasing from 92° 127°. lowest (6°) obtained coating containing both F-POSS. Topographical images showed essential role providing rough surface structure. optimal formulation consisted 10 wt.% particles 5 oil, resulting water 127°, 9°, approximately 42 days protection, an value 4.8 × 108 Ω·cm2. Remarkably, demonstrated exceptional durability terms properties, maintaining push-off strength 9.3 kPa even after 15 icing/de-icing cycles, confirming its desirable performance.

Pulsed terahertz spectroscopy is widely used in scientific research of fast processes various structures at nano-, meso- and macrolevels. Terahertz radiation has not been applied construction technologies until very recently. With the development spectroscopy, it successfully complements classical methods physical chemical analysis building materials for engineering purposes, especially heat-insulating a wide range density electrical insulating properties. These studies are currently relevant compositions effective thermal insulation based on wastes pulp paper industry, including types substandard raw materials.
