Nanoparticles Revolutionize Self-Cleaning Walls and Indoor Air Quality: Study by TU Wien and Italian Universities

New Paint Technology Cleans Walls and Improves Air Quality

A recent study published on phys.org highlights the development of titanium oxide nanoparticles that can clean walls and improve indoor air quality when added to paint. These nanoparticles were created by a research team from TU Wien and the Università Politecnica delle Marche in Italy.

When mixed with standard paint, the nanoparticles utilize sunlight to activate their self-cleaning properties. The nanoparticles work by binding substances from the air and then breaking them down afterwards. This innovative technology allows painted walls to not only clean themselves but also improve indoor air quality by eliminating pollutants.

Professor Günther Rupprechter from TU Wien explained that titanium oxide nanoparticles have the ability to bind and break down a wide range of pollutants, making them particularly useful for this application. The research showed that 96% of air and wall pollutants can be removed by exposing them to simple sunlight with the help of these nanoparticles.

One of the study’s authors, Qaisar Maqbool, highlighted that detailed analysis of the particles and their behavior before and after being added to wall paint was conducted to better understand the process. Further research is planned with the goal of creating a commercially available paint product using this technology.
