Title: Preparation and Properties of Ultrafine Porous Anodic Oxidized Aluminum Film
Abstract: The preparation and function of porous anodizing aluminum films with bigger area and strength as functional films were investigated using SEM and new progress.The anodic oxidized films having ultrafine pores were formed on aluminum foil by anodizing in 4% H 3PO 4 solution.And then the aluminum foil with porous anodic films were electrochemically etched in 3.5% HCl, therefore the strength of anodic films supported by aluminum base having etched pits is bigger than alone porous films.The barrier layer between porous films and aluminum base was cut and broken in 2% NaOH solution.Finally,the alumina films with aluminum base were heat treated at 350℃ to get dehydrated anodic films.
