摘要
以云母(001)为衬底,采用无机溶胶-凝胶法,通过加入表面活性剂十二烷基三甲基溴化铵(CTAB),在不同条件下制备了多孔VO2薄膜。采用SEM、FT-IR等手段分析了薄膜的表面形貌和热致相变性能。结果表明,膜的热处理工艺参数等对薄膜的表面形貌、颗粒尺寸及光学性能有重要影响,多孔VO2薄膜的形成与退火温度、保温时间及退火环境有关。
Porous vanadium dioxide films have been fabricated in different conditions on muscovite （001） sub- strates with the addition of surfactant cetyltrimethyl ammonium bromide （CTAB） by sol-gel method. SEM and FT-IR were used to investigate the morphology and therchromic properties of the VO2 films. The results reveal that annealing technical parameters have great effect on morphology, grain size and optical properties of porous VO2 films, and the synthesis of porous VO2 films is depend on annealing temperature, holding time and annea- ling atmosphere.
