摘　　要：以较高浓度的HF调控硝酸锌和六亚甲基四胺体系中ZnO的微观形貌,发现随着HF用量的增加,ZnO继发生短棒型、花型变化后最终变为蒲草型微纳结构;其形貌和润湿性用SEM和视频接触角测量仪进行表征。ZnO薄膜形貌的变化导致其润湿性发生相应变化,而且经紫外光照射处理后,蒲草型ZnO表面润湿性可以发生从疏水到超亲水的转变(CA^0°);黑暗放置7d左右,可以回到原来的疏水状态,而且可以反复多次。The effect of high concentration of HF on the ZnO micro/nanostructure in the mixture solution containing20 mL zinc nitrate（0.1mol/L）and 20 mL hexamethylenetetramine（0.1mol/L）was described.It was found that ZnO micrograss structures were obtained when high concentrations of HF were used,and they were characterized by scanning electron microscope（SEM））and static contact angles（CAs）.The hydrophobicity was decreased with the increase of the amount of HF.Furthermore,their reversible switching was achieved by alternation of ultraviolet（UV）irradiation and dark storage,and this process repeated several times without any obvious deterioration.
