摘要
以NH4F为电解质,分别以乙二醇,去离子水为电解液,用阳极氧化法制备了TiO2纳米管,考察了不同的电解液,电压,阳极氧化时间,电解质浓度等因素对TiO2纳米管形貌的影响,采用场发射扫描电子显微镜(SEM)对纳米管的形貌和结构进行表征,结果表明:乙二醇制备的纳米管比水基电解液排列有序,管径一致,管径更小;提高电压可使管状更加清晰;增长电解时间,更有利于纳米管的伸长;电解液浓度升高,腐蚀速率增高,会使管长降低。
Used NH4F as the electrlyote in ethylene glycol and water, prepared TiO2 nanotubes which orderly arranged by anodic oxidation. We Investigated the Influence of Different electrolyte,voltage,anodization time, electrolyte concentration,and other factors on the morphology of TiOa nanotubes. Observed the morphology and structure of the nanotubes by the field emission scanning electron microscope (SEM). The results show that : Nanotubes obtained in the organic electrolyte, uniform diameter,arranged in order.
