摘要

Unique packaging of Ag₂O on the surface of polycrystalline AgCl allows fabrication of a new useful, superhydrophobic composite material. This pure inorganic material with surface porosity of submicrometer aperture size fabricates air pockets, which make the composite material superhydrophobic. The new material behaves like lotus leaves, butterfly wings, or water strider’s leg in relation to superhydrophobicity. Visible light induces photoreduction of solid Ag₂O surface layer and generates Ag(0), making the composite surface superhydrophilic. Reoxidation of Ag(0) on the composite surface gives back the hydrophobicity that represents the redox-switchable wetting property of the material.

多晶氯化银的表面上独特的包装的Ag 2 O为允许一个新的有用的，超疏水性复合材料的制造。这与亚微米孔径大小的表面孔隙率的纯无机材料编造气泡，使复合材料超疏水。这种新材料的行为就像荷叶，蝴蝶的翅膀，或与超疏水水黾的腿。可见光诱导固体的Ag 2 O的表面层的光还原，并产生的Ag（0），使得复合材料表面超级亲水。的Ag（0）上的复合材料表面的再氧化还给表示的材料的氧化还原转换的润湿特性的疏水性。
