Violet tungsten oxide powder may be applied for the preparation of thermal absorption agricultural plastic film. At present, blown polyethylene film is a widely used and low-cost agricultural film, which has certain heat preservation, chemical stability, moisture resistance and many other characteristics. However, its heat absorption and heat insulation performance are not very good. Therefore, experts are studied to find that if a certain amount of violet tungsten oxide nanoparticles are added to the polyethylene film, it can have better…
