摘　　要：以云母(001)为衬底,采用无机溶胶-凝胶法,通过添加表面活性剂十二烷三甲基溴化铵(CTAB),以及加入同一元素族、不同粒径的无机盐离子Li+、Na+、K+和同一周期、不同价态的Na+、Mg2+、Al3+制备多孔VO2薄膜。采用SEM、FT-IR等手段分析薄膜的微观形貌特征和热致相变性能。结果表明,不同化合价、不同粒径的无机盐离子对多孔VO2薄膜的颗粒尺寸分布、微观形貌以及热致相变性能产生影响。Porous vanadium dioxide films had been fabricated by adding the same main group and different radius inorganic ions Li+,Na+,K+,the same cycle and different valence inorganic ions Na+,Mg2+,Al3+on muscovite (001)substratum with the addition of surfactant cetyltrimethyl ammonium bromide (CTAB)by sol-gel meth-od.SEM and FT-IR were used to analyze the morphology and thermochromic properties of the films.The results reveal that different valence and size inorganic ions have great effects on grain size,morphology and thermo-chromic properties of porous VO2 films.
