摘要
采用扫描电子显微镜、χ 射线衍射分析、电子探针及光谱测试分析技术 ,研究了硫酸溶液中铝阳极氧化多孔膜的结构、成分及红外吸收特性 .结果表明 :在近红外波段多孔膜具有良好的透光特性 ,而在130 0~ 70 0cm-1波段则有良好的吸收特性 ,且通过宏观调节膜层厚度及孔径 ,可对膜层的红外透射率进行调节 .
The structure, elemental composition and infrared wave absorption of the porous alumina film in the sulfuric acid solution are studied with the help of the scanning electron microscope, χ ray analysis, electronic probe and spectrophotometry. It is shown that the porous alumina film is transparent in the short infrared region and can absorb the infrared wave in 1 300~ 700 cm -1 . The transmission can also be controlled by changing the thickness and the radius of the porous film.
