제목 Influence of Polyacrylic Acid in the Synthesis of Tungsten-Doped Vanadium Dioxide Nanomaterials.
초록 Doping of vanadium dioxide (VO2) with tungsten has been a promising route for reducing the metal-insulator phase transition (MIT) of VO2 at around 68 °C to room temperature. The resulting decrease in MIT makes WxVO2 as an ideal candidate for thermochromic window materials by reflecting near‒infrared light at room temperature while transmitting visible light. Another issue of VO2 is to reduce each particle size. For the application to thermochromic windows, nanoparticles of VO2 are highly required to reduce the haze effect by light scattering and to present prompt phase transition under environmental temperature variation. In this study, we synthesize VO2 nanoparticles with vanadium pentoxide (V2O5), oxalic acid (OA) and polyacrylic acid (PAA). We select PAA because it is miscible with OA, a reducing reagent for V2O5 to VO2. We investigated the influence of PAA on the morphology and crystal structure of tungsten-doped vanadium oxides.
