Researchers Develop Self-Cleaning Paint Using Coated Titanium Dioxide Nanoparticles
LONDON - A team led by researchers from University College London (UCL) has developed a new paint that makes robust self-cleaning surfaces. The coating can be applied to clothes, paper, glass and steel, and when combined with adhesives, maintains its self-cleaning properties after being wiped, scratched with a knife and scuffed with sandpaper.
Self-cleaning surfaces work by being extremely repellent to water but often stop working when they are damaged or exposed to oil. The new coating creates a more resilient surface that is resistant to everyday wear and tear, so could be used for a wide range of real-world applications from clothing to cars, say the researchers.
