英文摘要： Light-induced controllable conversion of wettability have been extensively studied and much progress has been made in recent years. However, the the conversion of wettability under light wastes long time which has been a challengeable problem for biomimetic smart nano-interface materials, and very few researches have been reported to enhance the conversion of wettability. This work was propounded to improve the wettability change of film under light. It has been reported that semi-conductor oxides show intriguing wettability conversion property under light. And heterogeneous materials might have produced extraordinary surface and interface properties. Therefore, it is predictable to enhance the wettability conversion of ZnO film under light through embeding heterogeneous materials into ZnO film combining with surface microstructure of ZnO film. This reseach containes undermentioned aspects: 1) exploring the effect factors of wettability conversion under light; 2) investigating the method to fabricate the ZnO film with novel surface microstructure, and obtaining superhyphobic ZnO film; 3) investigating the method to enhance the wettability conversion of ZnO film under light; 4) exploring the mechanism of improving wettability conversion through doping heterogeneous materials into ZnO film; 5) investigating the se
