Transparent metamaterial for energy-efficient regulation in building can clean itself like a lotus leaf

Researchers at the Karlsruhe Institute of Technology (KIT) introduce a polymer-based material with unique properties in the journal Nature Communications. This material allows sunlight to enter, maintains a more comfortable indoor climate without additional energy, and cleans itself like a lotus leaf. The new development could replace glass components in walls and roofs in the future. The research team has successfully tested the material in outdoor tests on the KIT campus.
