Superhydrophobic to icephobic properties of micro/nano-structure composite surfaces

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.
