As a representative of transition metal N-type semiconductor materials, purple tungsten oxide (WO2.98) ultrafine powder can not only be used to produce energy storage electrode materials, but also can be used to manufacture high-performance film. As far as agricultural films are concerned, films containing WO2.98 particles have better thermal insulation and light transmittance.
Film mulching is an effective way to increase agricultural production. Its most important function is to have good thermal insulation and increase the ground temperature, which is not only conducive to early sowing, early harvest, and expansion of the cultivation area of some crops, but also prolongs the growth period of some crops, thereby greatly increasing the yield.
The level of ground temperature is determined by the absorption and dissipation of ground heat. When receiving solar radiation during the day, the ground absorbs more heat than it emits, so the ground temperature rises; at night, the heat emitted by the ground is higher than the atmospheric radiation received, so the ground temperature decreases.
The ways to further improve the thermal insulation of ordinary films are as follows: one is to improve the geothermal radiation barrier property of the film; the other is to increase the solar radiation transmittance of the film. Generally speaking, infrared absorbers and visible light transmittance agents can be added to film products, which can increase the ground temperature while increasing the geothermal radiation barrier.
Violet tungsten oxide has a strong absorption of near-infrared rays and a high transmittance of visible light, so it has become the preferred material for a new generation of mulch films, which can greatly improve the thermal insulation performance and light transmittance of film products.
