摘要
超疏水表面的制备及其抗结冰性能受到广泛关注,但超疏水表面的微观结构及浸润性能对其抗结冰性能的影响规律仍无定论。利用飞秒激光在金属铜表面制备了一系列具有不同微观特征的微纳米结构,这些表面经过化学修饰后都具有超疏水性,同时对水具有不同的粘附性。系统研究了这些超疏水表面的抗结冰性能,结果表明,这些超疏水表面在低温(-5 ℃,-10 ℃)下都能延缓表面水滴的结冰过程。超疏水表面对水的粘附性对其抗结冰性能有显著影响,粘附性较小的超疏水表面比高粘附的超疏水表面具有更为优异的抗结冰性能。
Abstract
In recent years, the anti-icing properties of superhydrophobic surfaces attract tremendous attention of researchers. However, the effect of surface microstructures and wettabilities on their anti-icing properties is still controversial. Different microstructures on copper surface are fabricated by a femtosecond laser. After surface chemical modification, these surfaces show superhydrophobicity combined with different adhesion to water. Their anti-icing properties are studied. The result shows that all these superhydrophobic surfaces delay the ice formation in low temperatures (-5 ℃,-10 ℃). In addition, the superhydrophobic surface adhesion to water affects the antiicing property. Low superhydrophobic surface adhesion to water benefits their anti-icing property.
