摘　　要：通过加入丙二醇改变丙二酸电解液的黏稠度。维持丙二酸的浓度为0.8 mol/L,丙二醇的体积比分别为0%、30%、50%、70%、100%,制备出具有鲜艳结构色的阳极氧化铝(AAO)薄膜。结果表明:随着电解液黏稠度的提高,最高氧化电压逐渐升高,AAO薄膜模板的孔间距逐渐增大。不同黏稠度的电解液中制备的AAO薄膜表面光波反射峰位置不同。对此,利用布拉格反射公式进行了分析,进而对有无铝基支撑时薄膜颜色的改变做出了解释。Adding propylene glycol to change the viscosity of malonic acid electrolyte.The concentration of malonic acid was maintained at 0.8 mol/L and the volume ratio of propylene glycol was 0%,30%,50%,70%and 100%,respectively,iridescent anodic aluminum oxide(AAO)films were prepared.The results showed that the maximum oxidation voltage and the interpore distance of AAO films gradually increased with increasing of the viscosity of electrolyte.The position of light-wave reflection peaks on the surface of AAO films prepared in the electrolyte with different viscosity was different.This phenomenon was analyzed using Bragg reflection formula,and then to explain the change of film color with or without aluminum substrate support.
