Nano violet tungsten oxide may be used for the preparation of thermal absorption agricultural plastic film. For example, it may be applied to prepare a land cover film for agricultural and horticultural use. Such thermal absorption agricultural film can absorb solar heat from sunlight through the violet tungsten oxide nanoparticles (infrared absorbing material particles). The infrared rays are absorbed by the film, the film temperature rises, the radiant heat also increases, and the temperature of the covered soil rapidly rises.…
