Polyamide 66 (PA66) nanotubes with an array structure were prepared by infiltrating a solution of normal molecular weight PA66 into anodic aluminum oxide (AAO) templates with a pore diameter of 200 nm. The results of field-emission scanning electron microscopy (FESEM) demonstrate that PA66 nanotubes with a wall thickness of about 60 nm can be fabricated by a solution-wetting method and PA66 nanotubes and nanowires can be obtained by a melt-wetting method at different temperature. We also find that PA66 nanotubes have the “super plasticity” for the crystalline belts in their wall may arrange by spiraling and rounding style. Thermogravimetric analysis (TGA) indicates the nanotubes have a better thermal stability than bulk polymer PA66. The mechanism of forming polymer nanotubes by polymer melt-wetting method has been proposed.

Indium antimonide nanowires were synthesized by electrochemical deposition using anodic aluminum oxide template in the presence of gold film as conductive layers. Field emission scanning electron microscopy and energy dispersive X-ray spectrometry measurements were carried out to investigate the effect of adhesive insulated tape covered below the conductive layer. Results showed that the anodic aluminum oxide template covered with insulating tapes had better morphology with less presence of overgrown rough film on the topside of the anodic aluminum oxide template and it exhibited a smoother nanowire sidewall as compared to the uncovered ones. Additionally, the unique properties of anodic aluminum oxide were controllable pore diameter with a narrow size distribution at some intervals. It was evident from the energy dispersive X-ray spectrum that the nanowires synthesized from the covered template condition exhibited better InSb composition and stoichiometric ratio compared to the uncovered template condition.

Abstract Anodic aluminum oxide (AAO) has been fabricated in the 0.3 M oxalic acid at voltage range 20-60 V and temperature range of 35-50oC. The resulting nanoporous alumina surfaces were characterized by high resolution scanning electron microscopy, and the images were quantitatively analysed by means of an innovative approach based on fast Fourier transform. The influence of operating anodization voltage and electrolyte temperature on nanopores geometry (pore diameter, interpore distance, porosity, pores density) and arrangement has been studied in details and compared to literature data and theoretical calculations. It was found that independently from the temperature, the best arrangement of the nanopores is for anodic aluminum oxide formed at voltages ranging from 40 to 50 V. Moreover, it was found that pore diameter and interpore distance increase linearly with voltage, what is in line with the literature data.
