摘要
以磷酸溶液为电解液、以高纯铝为阳极,采用两步阳极氧化法制备氧化铝模板。扫描电子显微镜(SEM)对其表面形貌分析表明,氧化铝膜为多孔结构,膜孔径随着阳极氧化电压的增大而不断增大。对阳极氧化电流密度变化分析证实,铝的阳极氧化经历了三个阶段:阻挡层的生成、多孔层的形成和多孔层的稳定生长。以制备的氧化铝膜为阴极、锌片为阳极,以硝酸锌和硼酸的混合液为电解液,采用交流电沉积方法制备了针状氧化锌纳米线。
Aluminum oxide templates are prepared by two-step electrochemical anodizing process with phosfilm involves three stages: formation of barrier layer, germination and stable growth of porous layer. Moreover, needle zinc oxide nanowires are prepared by electrodeposition with aluminum oxide as cathode,zinc plate asanode, the mixture of zinc nitrate and boric acid as electrolyte.
