Mo-doping Tungsten Oxide Electrochromic Film Applied for Smart Glass

Mo-doping tungsten oxide electrochromic film may be applied to produce smart glass with high heat insulation performance so that it has received more and more attention in the field of construction. According to experts, such electrochromic thin film can be achieved by screen printing and heat treatment. And Mo-doped tungsten oxide nano slurry should be prepared at first. So, how to prepare Mo doped tungsten oxide nano slurry?

Preparation of Mo-doped Tungsten Oxide Nano Slurry

Ethylcellulose was dissolved in ethanol at room temperature and stirred for 1 h to obtain a clear, transparent sol. The ratio of ethanol to ethylcellulose was 10:1. The Mo-doped tungsten oxide nanoprecipitate and terpineol were added together to the ethylcellulose transparent sol, and subjected to rotary evaporation at 90 °C to evaporate the organic solvent to obtain Mo-doped tungsten oxide nano slurry. Wherein, the mass ratio of terpineol, ethyl cellulose sol and molybdenum doped tungsten oxide nanoprecipitate is 5:4:1.
