Tungsten oxide powder may be used for the preparation of thermal absorption agricultural plastic film, which has good heat preservation effect and heat insulation effect. And thus such thermal absorption film has a wider range of uses. The obtained agricultural plastic film has the advantages of stronger toughness, strength and wind resistance than the general agricultural film. So, the new agricultural plastic film of tungsten oxide has long service life with excellent performance. In other words, in the preparation of agricultural film, adding a certain amount of tungsten oxide nanoparticles can greatly extend the service life of common agricultural film.
In addition, the obtained new agricultural film also has excellent continuous fog-eliminating and dripping ability. That is to say, an appropriate amount of tungsten oxide nanoparticles can make the agricultural film have the property of suppressing the generation of mist, and the defogging flow period of the agricultural film can even as long as the life of agricultural film.
