通过在铜片表面沉积蜡烛灰涂层成功构建了纳米结构超疏水表面，该表面在室温(23±2)℃下与水滴的接触角为160°，滚动角为1°.研究了超疏水铜表面在低温条件下的抑冰性能，结果表明，在(－40±10)℃时将50μL水滴从5 cm的高处滴至普通的铜表面2 s开始结冰，而滴至超疏水铜试样(3 cm×3 cm×0．2 mm)表面的水滴可以快速滚动，从滚动直至滚落超疏水铜试样表面所需的时间比水滴开始结冰所需的时间(50 s)短，水滴未在超疏水铜试样表面结冰.通过测试冰与材料的黏附力，发现普通铜表面与冰的黏附力是超疏水铜表面与冰的黏附力的4．9倍.此外，在融冰的过程中发现，结冰的水滴在常温下稍微融化，在微风的作用下或稍微倾斜6°就能从超疏水铜表面滑落下来，表明超疏水铜表面比普通铜表面具有更好的抑冰性能.
A superhydrophobic surface with nano-structure was obtained by depositing candle soot on a copper surface.The water contact angle and sliding angle of the as-prepared superhydrophobic surfaces were respective-ly 160 and 1°under common condition (23±2)℃.The anti-icing property of the superhydrophobic copper sur-face was studied.When the samples were transferred to a refrigerator at (-40±10)℃,the water droplets (50μL)which dropped from the height of 5 cm to the superhydrophobic copper surface (3 cm×3 cm×2.5 mm) rolled quickly off the surface,which would be frozen on the ordinary copper surface (t=2 s).The water drop-lets were not frozen before slipping off from the superhydrophobic copper surface result of the shorter roll time than the frozen time (t=50 s).The testing of ice shear stress showed that ice shear stress of common copper surfaces was 4.9 times of the superhydrophobic copper surface.In addition,the ice-water mixtures could slip off the superhydrophobic copper surface when suffered the breeze or slightly tilted 6°at common condition.The re-sults showed that the anti-icing property of the superhydrophobic copper surface was better than the common copper surface.
