Abstract

Superhydrophobic surfaces have proven effective in mitigating ice formation on substrates. This study aimed to experimentally investigate the effects of the surface structure of selected metal substrates on the anti-icing performance. Superhydrophobic surfaces were fabricated on aluminum, copper, stainless steel, and titanium substrates using a spray coating technique with superhydrophobic tridecafluorooctyl triethoxy silane (FAS)-functionalized colloidal silica nanoparticles. The surface wettability, surface morphology, and chemical analysis of the coated surfaces were reported. The results demonstrated successful deposition of silica nanoparticles on all substrates, significantly improving the anti-icing property of the coated surfaces. When compared with uncoated surfaces, the droplet icing times of the coated aluminum plate (C-Al), of the coated copper plate (C-Cu), of the coated stainless steel plate (C-SS), and of the coated titanium plate (C-Ti) significantly enhanced by 751%, 795%, 830% and 1320%, respectively. Also, a heat transfer model was also developed to explain the anti-icing phenomenon.

超疏水二氧化硅纳米结构金属基板的防冰性能研究

超疏水表面已被证明在减缓基底上结冰方面是有效的。本研究旨在通过实验研究所选金属基底的表面结构对防冰性能的影响。采用超疏水十三氟辛基三乙氧基硅烷（FAS）功能化胶体二氧化硅纳米颗粒喷涂技术，在铝、铜、不锈钢和钛基底上制备了超疏水表面。报道了涂层表面的润湿性、表面形态和化学分析。结果表明，二氧化硅纳米颗粒成功沉积在所有基底上，显著提高了涂层表面的防结冰性能。与未涂覆表面相比，涂覆铝板（C-Al）、涂覆铜板（C-Cu）、涂覆不锈钢板（C-SS）和涂覆钛板（C-Ti）的液滴结冰时间分别显著提高了751%、795%、830%和1320%。此外，还建立了一个传热模型来解释防冰现象。
