Uzbek Scientists Create Smart Film for Greenhouses with Temperature Regulation

Scientists from the Institute of Materials Science of the Academy of Sciences of Uzbekistan have developed innovative nanoparticles that are added to greenhouse film. This technology allows for effective temperature regulation inside greenhouses without the need for additional heating, contributing to reduced energy costs and increased yields.

How the New Technology Works

According to the researchers, the nanoparticles convert ultraviolet light into near-infrared radiation, which generates heat at a level of 17–22 degrees Celsius. This helps maintain optimal temperature conditions in greenhouses during winter — even when the outside temperature is between -3 and -7 degrees Celsius, while in regular films, the temperature only rises to 0…+2°C. In summer, this film lowers the temperature inside the greenhouse by approximately 5–8 degrees, helping to reduce overheating.

Advantages and Prospects for Application

The implementation of this technology offers several advantages for farmers. According to the scientists, photosynthesis in plants is significantly accelerated, ensuring faster growth — by one and a half to two times. Additionally, using this film allows for more than a 60% reduction in energy consumption, a 35–50% increase in yield, and water savings during irrigation of up to 30%, and when using hydrogels, up to 90%. At the same time, the film becomes three times stronger, enhancing its durability.

The new technology has already been tested in the Tashkent, Jizzakh, Fergana, and Andijan regions. Furthermore, large-scale trials are ongoing in China across various climatic zones, involving specialists from the Shanghai Academy of Agricultural Sciences.

The Institute has reached an agreement with the Chinese company Shanghai Daedon Science and Technology Ltd. to launch joint production of nanopowders in Uzbekistan. According to plans, the first ton of nanoparticles will be produced in 2025, and by 2026, ten tons will be made. In the long term, there are plans to build a factory capable of producing up to 2000 tons of nanoparticles annually.
