采用水热法系统研究了基底预处理(基底铺膜、不铺膜吹氮气处理和盐酸浸泡处理等)方式对于制备ZnO微/纳米管阵列的影响;结合ZnO晶体的微观结构,探讨了基底特征与ZnO微/纳米管阵列生长的内在联系.结果表明,采用高纯氮气和盐酸浸泡预处理基底均能制备得到ZnO微/纳米管阵列,并且这两种预处理方法制备出的纳米管在尺寸、形貌和分布上有所不同.ZnO微/纳米管成管机理研究表明,ZnO顶部锌终端对于生长微/纳米管起着决定性作用.
The effects of substrate pretreatment (substrate filming, unsplit filming nitrogen treatment and hydrochloric acid soaking treatment) on the preparation of ZnO micro / nano tube arrays were investigated by hydrothermal method. The microstructure of ZnO crystals was investigated to investigate the characteristics of substrate And ZnO micro / nano-tube array.The results show that ZnO micro / nano-tube array can be prepared by pretreatment of substrate with high purity nitrogen and hydrochloric acid soaking, and the nanotubes prepared by these two pretreatment methods have the same advantages in size , Morphology and distribution are different.ZnO micro / nanotube tube forming mechanism studies have shown that the top of ZnO zinc terminal for the growth of micro / nanotubes play a decisive role.
