    • 摘要: 利用高纯铝片采用两步阳极氧化法制得排列高度有序、尺寸可控的单通氧化铝(anodic aluminum ox-ide templates,AAO)模板,且纳米孔呈六方形结构.分别探究了预处理条件、氧化次数、扩孔时间等对 AAO 模板尺寸及有序性的影响.结果表明,预处理利于纳米管形成高度有序结构,并发现二次阳极氧化法比一次阳极氧化法制备的纳米管排列更有序且孔径均匀;在0~75 min 内,管孔径与扩孔时间呈线性关系,酸溶液对孔的腐蚀速率为0.601 nm/min,在0~120 min内,管长度与二次氧化时间呈线性关系,生长速率为0.28 μm/min;最佳电解液浓度确定为0.3 mol/L.为后续制备非对称丝岛状骨组织再生高分子薄膜奠定了良好基础.%Single-pass anodic aluminum oxide (AAO)templates were fabricated by a two-step anodization meth-od on high-purity aluminum (Al)plate,which had an amorphous and highly ordered structure composed of hexagon cross-sectional nanotubes.The factors influencing the nanotube size and orderliness of the AAO tem-plate were studied and analyzed.The results showed that pretreatments on Al plates made good difference for the obtained nanotubes.It is interesting that compared to one-step anodization,using two-step anodization could get AAO templates with a better ordered and more uniform nanotube array,for which the average pore diame-ter kept a linear relation to the acidic treatment time in 75 min with a corrosion rate of 0.601 nm/min,and the same to the length of nanotubes reaped in 120 min,together with a nanotube growth rate of 0.28 μm/min.Al-so,the optimal concentration of electrolyte was determined as 0.3 mol/L.The results confirmed that a single-pass AAO template were successfully prepared,which makes the fabrication of polymer membrane with asym-metric and fibre-island structure to guide bone tissue regeneration possible in the following study.

    • 摘要: 采用氧化铝模板法电沉积制备钴纳米线,并研究了沉积电位对钴纳米线的表面形貌和磁性能的影响.研究发现:电沉积钴纳米线的过程中,沉积电位与生长速率相互影响和制约.沉积电位太低,团聚作用明显,得不到钴纳米线;沉积电位增大,晶体表面能降低,有利于钴纳米线的生长,提高磁性能.然而,当沉积电位大于1.4V时,钴纳米线疏松短小,导致矫顽力下降.

    • 摘要: 文章中,我们以阳极氧化铝膜作为模板,通过直流电化学沉积的方法成功地制备出了Fe-Co-Ni三元合金纳米线有序阵列.通过纳米线阵列的形貌和结构的研究,发现Fe-Co-Ni纳米线直径均一且与模板孔径相等,具有多晶结构.最后通过振动样品磁强计(VSM)对Fe-Co-Ni纳米线阵列磁性进行了研究,结果发现,纳米线阵列在平行和垂直方向上的矫顽力和剩磁比均有所不同,表现出较强的磁各向异性,这是由其大的长径比而引起的大的形状各向异性和本身较大的磁晶各向异性决定的.

    • 摘要: 阳极氧化铝(AAO)模板具有高度有序的纳米孔阵列,在制备一维纳米材料方面有广泛的应用,阳极氧化铝模板法是制备纳米线及纳米管的重要方法.文章基于二次阳极氧化的方法实验制备了柱面氧化铝模板,围绕氧化铝模板纳米孔径的大小和有序性,利用扫描电子显微镜(SEM)对所形成纳米孔的形貌特征进行观测,并与平面阳极氧化铝模板的纳米孔进行比较,分析了氧化铝模板表面纳米孔的生长情况及其形成机理.结果表明:高度有序的锥形纳米孔阵列会沿着柱面直径辐射生长;纳米孔没有出现弯曲和分叉现象,柱面AAO模板内外表面纳米孔径大小分别为40和55 nm;纳米孔径变化率为0.5 nm/μm,膜厚约为30μm,通过调整柱面铝片的曲率半径和阳极氧化时间,可以控制锥形纳米孔径大小范围在60~120 nm之间.%Anodic aluminum oxide (AAO)has been widely used in the preparation of one dimension and zero dimensional materials due to its highly ordered nano hole array.Anodic alumina template method is an important method to prepare nanowires and nanotubes.This paper reports the fabrication of cylindrical aluminum oxide template based on the two-step anodization method in sulfuric acid solution.This study makes the observation around the size and the order of the nano pore size of the alumina template by using the scanning electron microscopy (SEM),and then compares it with the plane anodic aluminum oxide template and explores the growth of nano pores on the surface of alumina template.The results show that straight nanohole arrays have been grown along the radical directions of the cylindrical alumina membrane without bending or branching at all.The inner and outer surfaces of cylindrical AAO template nano hole size are 40 nm and 55 nm.The change rate of the nano hole is 0.5 nm/μm (the film thickness is about 30 μm ).By adjusting the radius of curvature of the cylindrical aluminum sheet and anodizing time,the radius of the conical nanopore size can be controlled in the range of 60-120 nm.
