Abstract
Due to the regular porous nanostructure,porous alumina is always used as templates to prepare the kin of nanomaterials.Therefore,it is very important to investigate the preparation and physical property of porous alumina.Porous alumina was fabricated by anodization in oxalic acid solution.The micro-structures,crystalline state and transmissivity of porous alumina were investigated.By scanning electron microscopy(SEM) observation,distribution of pores was found to be ordered and pores were precisely vertical to their substratum.X-ray diffraction(XRD) demonstrated that the samples were non crystalline structure.In the visible and infrared wavelength range,porous alumina have excellent transmittivty.
