Description
Nanoporous alumina fabricated by the anodizing of Al provides unique, advantageous characteristics such as uniformity, high pore d., controllable pore dimensions, highly ordered structure and simple synthesis procedures. Nanoporous alumina membranes have applications in diverse fields such as tissue engineering, drug delivery, biosensors and templates to synthesize nanowires or nanotubes. The performance of nanoporous surfaces and nanoporous membranes is highly dependent on the pore morphol., size and chem. as well as their d. and homogeneity. One of the fascinating aspects of anodized alumina nanoporous structure is its tunability in pore size, pore d., inter-pore distance and pore depth by simply changing the anodizing parameters, such as current, voltage, time, electrolyte chem., electrolyte concn. and temp. To control the anodizing of Al and obtain desirable properties, an understanding of anodizing conditions on the film characteristics is important. In this study a statistical anal. of the effect of process variables on the nanoporous structure of anodized alumina is examd. Such studies can be extended to anodizing other materials such as niobium and tantalum for various applications including energy storage.
