| The purposes of this dissertation are to study the electrochemical preparation, characterization of nanowire arrays, nanotube arrays, nanohole arrays and their properties. The influencing factors, electrodeposition mechanism and related properties of nanoarrays assembled by template-electrodeposition technique were investigated in this dissertation based on electrochemical techniques and modern physical methods. And the Cu/Ni multilayered nanowire arrays embedded in the nanochannels of aluminum anodic oxide membrane (AAO) were successfully fabricated by direct current (D.C.) electrodeposition with double bath technology (D.B.T). The research contents and the gained chief achievements are as follows:First of all, the microstructure of anodic aluminum oxide (AAO) film was particularly studied by AFM. It shows that except hexagonal pore arrays in AAO film there is a small microstructure like plum blossom along the surface of pore wall. The nanopore arrays are actually a highly ordered plum blossom arrays patterns. From the point view of the electric field, the formation cause of this microstructure was discussed in detail. For this AAO film microstructure, high yield amorphous andγ-Al2O3 alumina nanowires could be obtained by etching AAO films. And the effect of pore diameter, barrier layer, load and compression displacement on the nanomechanics properties of AAO film was studied. This work hasn't been published to the best of our knowledge.The polyaniline (PANI) nanotubles and nanowires arrays were assembled in the AAO template nanoholes by diffused polymerization and electrochemical polymerization. The morphology, structure and property of PANI nano-array were characterized by many kinds of physical methods, such as SEM, TEM, XRD and so on. The results show that in diffused polymerization, the nascent polymer is preferentially deposited on the pore walls and then grows by layer upon layer along the pore walls until the solid nanowires are formed. The PANI nanowires and nanotubles structures are composed of both the crystalline phase and the amorphous phase. The conductivity of individual PANI nanowire (22.1 S·cm-1) was calculated. In electrochemical polymerization, the rates of nanowires growth in nanoholes are nearly equal and the rate of the hole embedded is about 95 %. In the potential range–0.1 ~ 0.85 V, the polyaniline nanowires arrays have certain electrochemical activity.Ni nanowire arrays were prepared by direct current electrodeposition in AAO template from a composite electrolyte solution. SEM, TEM, EDS and VSM were employed to characterize the morphology, structure and property of Ni nanowires arrays. It is found that each nanowire is essentially a single crystal with a preferred〈111〉direction. These nanowires have a uniform diameter of approximate 70 nm and the rate of the hole embedded is about 80 %. Hysteresis loops of Ni nanowires arrays show that its easy magnetization direction is perpendicular to the sample plane.Cu/Ni multilayered nanowires with different wavelenth were prepared by direct current electrodeposition in AAO template with double bath technology (DBT). The morphology, structure and property of Cu/Ni multilayered nanowires arrays were studied by some physical methods. The results shows that the diameter of the Cu/ Ni multilayered nanowires is about 120 nm and the Cu/ Ni multilayered nanowires have well-defined layers. The Ni segment and Cu segment are single crystal. The longer of the deposition time of segment is, the thickness of segement would be increase. Hysteresis loops of Cu/Ni nanowires arrays show that its easy magnetization direction is also perpendicular to the sample plane.
