摘要：Ice formation on critical infrastructure such as power transmission lines, wind energy systems, and aerospace components poses substantial safety hazards and incurs considerable economic losses. Conventional anti-icing/ deicing technologies suffer from inherent limitations, including low efficiency, high energy consumption, and potential environmental contamination. To address these challenges, this study developed a multifunctional composite coating through solution blending and spray-coating methodologies, which integrates modified silica nanoparticles (SiO2) and multi-walled carbon nanotubes (MWCNTs), with 1 H, 1 H, 2 H, 2H-Perfluorodecyltri-methoxysilane (PDTMS) utilized for surface hydrophobic modification. Comprehensive characterization results indicated that the coating exhibited a water contact angle (WCA) of 151 degrees, the sliding angle is 3.7 degrees, demonstrating exceptional super hydrophobicity. The freezing delay time of water droplets on the coated surface was 3.15 times longer than that on the bare substrate, which is attributed to the hierarchical micro-nanostructured surface topography. Under solar irradiation of 1 kW/m2 for 1500 s, the coating displayed a prominent photothermal response, with its surface temperature increasing to 46.4 degrees C. In addition, frozen droplets on the coating completely melted within 184 s under these conditions, which is ascribed to the synergistic effects of photo-thermal conversion and interfacial energy modulation. The integration of photothermal-responsive SiO2-MWCNT hybrids and a low-surface-energy architecture derived from PDTMS synergistically enhances both anti-icing delay performance and active deicing efficiency. This dual-functional coating system offers a promising and sustainable solution for mitigating ice accumulation on wind turbine blades, thereby addressing critical operational challenges encountered under extreme climatic conditions.
