摘要：通过在基材表面喷涂环氧树脂作为黏合剂，然后喷涂炭黑纳米粒子、聚二甲基硅氧烷（PDMS）以及十
七氟癸基三乙氧基硅烷（PFDTES）的共混液制备了一种炭黑/PDMS 光热超疏水涂层。炭黑纳米粒子提供光热
性能并使涂层具有微纳粗糙结构，结合 PFDTES 较低的表面能使涂层获得超疏水性能。制备涂层表面的水滴接
触角高达 161，滚动角低至 1.4，呈现优异的超疏水性能，从而使水滴在玻璃表面结冰的时间由 30 s 延迟到 160 s。
涂层中炭黑所提供的光热转换效应使其表面的冰在太阳光照射下能迅速融化，并随自重自动脱落。此外，涂层
的自清洁性能可防止表面在户外应用时遭受污染，有利于保护涂层的光热转换性能和长期光热除冰功能。

Abstract: A carbon black/PDMS photothermal superhydrophobic coating was prepared by spraying the
substrate with epoxy resin as binder, followed by coating with a mixture of carbon black nanoparticles,
polydimethylsilane (PDMS) and 1H,1H,2H,2H-perfluorodecyltriethoxysilane(PFDTES).Carbon black
provided photothermal properties and made the coating have micro/nano rough structure, while PFDTES
with the low surface the coating gave superhydrophobic properties. The contact angle and sliding angle of
the water droplets on the surface of the coating reaches 161 and 1.4, indicating that the prepared
coating had excellent superhydrophobic properties. The coating caused the freezing time of water
droplets on the surface of glass delay from 30 s to 160 s. The photothermal conversion effect provided by
the carbon black in the coating made the ice on the coating surface quickly melted under sunlight
irradiation and fall off automatically due to its own weight. Additionally, the self-cleaning property
of the superhydrophobic coating prevented the surface from being polluted during outdoor application,
which is conducive to protecting the photothermal conversion property and long-term photothermal
deicing function of the coating.
Key words: carbon black; superhydrophobicity; photothermal effect; anti-icing/deicing; self-cleaning;
