Scientists from Shanghai Jiao Tong University in China have come up with a unique cotton material that can clean itself when left under ordinary sunlight. The fabric includes a coat of nanoparticles made from a compound of titanium dioxide, nitrogen, silver and iodine. From a test experiment, the special coating was able to remove an orange stain when exposed to sunlight for just two hours. Furthermore, the coating remained intact even after washing and drying.
Researchers Mingce Long and Deyong Wu published their findings in the American Chemical Society Journal Applied Material & Interfaces. However, it is not expected that the breakthrough invention will be hitting retail shelves anytime soon.
