基于聚丙烯酸为模版的铜基氧化物气凝胶的制备及表征方法,通过引入聚丙烯酸米增加制离子的自由长度,得到了具有三维网络结构的制基氧化物气凝胶,该气凝胶经不同的温度热处理后,由于有机物聚丙烯酸被逐渐灼烧完,导致其比表面积、孔径、孔体积逐渐变小,并且晶型也随温度的变化而变化,并最终得到了氧化铜气凝胶。 Based on the preparation and characterization of polyacrylic acid as a template for copper-based oxide airgel, polyacrylonitrile was introduced to increase the free length of the system ions to obtain a system-based oxide airgel with three-dimensional network structure. The airgel After heat treatment at different temperatures, as the polyacrylic acid is gradually burned, the specific surface area, pore size and pore volume become smaller and the crystal form also changes with the temperature. Finally, the copper oxide airgel .
