Embodiment 1
[0022] Make 2.5g tungstic acid and 6.35g citric acid into an aqueous solution at a molar ratio of 3:1, continuously stir at 60°C, and then adjust the pH to 9 with ammonia water to form a tungsten trioxide / citric acid chelate solution . The solution was heated at 60° C. for 24 hours to generate a gel-like precursor, and was calcined in air in a muffle furnace at a high temperature of 700° C. for 6 hours to generate tungsten trioxide nanopowder. Accurately weigh 1.2g of tungsten trioxide nanospheres and disperse them in 25ml of absolute ethanol, and add 20ml of an ethanol solution of KH-570 silane coupling agent dropwise (concentration: 0.05g / ml). Then, under the condition of a water bath at 35° C., after reacting for 36 hours, vacuum drying at 40° C. overnight, the purified tungsten trioxide nanopowder treated with the coupling agent was obtained. In a three-necked flask equipped with a reflux condensing device, ultrasonically disperse 1.0 g of tungsten trioxide nanopowder tre...
Embodiment 2
[0025] Same as Example 1, but the concentration of KH-570 was changed to 0.05 g / ml, and the amount of vinylimidazole monomer was changed to 15 ml.
Embodiment 3
[0027] Same as Example 1, but the concentration of KH-570 was changed to 0.1 g / ml, and the amount of vinylimidazole monomer was changed to 30 ml.
