Fabrication and characterazation of anodic alumina with tapered porous structure
摘要
Abstract
A method to fabricate highly ordered tapered porous anodic alumina (PAA) templates in mixed solution which contains phosphoric acid and oxalic acid was presented. Firstly,highly ordered PAA templates with interpore distance of 495nm were fabricated by two-step method. On this basis, ordered tapered PAA templates with different aspect ratios were fabricated by alternately performing anodization process and pore widening process. Results showed that the aspect ratio of tapered PAA templates is linearly related to the total anodizing time,which could reach more than 100. And the relationship between tapered PAA morphology and partial anodizing time/partial pore widening time was also discussed in detail. The special structure of nano-template could expand the applications of PAA templates in fabricating metal or semiconductor nanowires,photoelectric materials and polymer materials.关键词
