通过软复型和水热法制备出一种由有机材料和ZnO纳米棒组成的微纳米结构复合表面,这种表面的微米结构是周期为300μm、高度为70μm的锯齿状结构, ZnO纳米线的直径为300~500 nm,长度为2~3μm.这种有机材料和ZnO纳米线复合成的表面经过全氟硅烷修饰后,具有良好的低黏滞特性和低温超疏水性(约为150°)以及较长的结冰延时性(6000~7630 s),实验结果对设计表面低温疏水/疏冰材料具有参考价值.
A micro/nano-structure surface which composed of organic materials and ZnO nanohairs was obtained by replica method and hydrothermal method. The cycle of the micro-structure is about 300 μm and the height of micro-structure is about 70 μm. The length and diameter of nano-structure are 2—3 μm and 300—500 nm, respectively. The results show that the micro/nano-structure surfaces have low adhesion, low temperature superhydrophobic properties and long icing delay time. This study has a good reference value on the design of hydrophobic/icing delay materials.
