To prevent your clothes from becoming stained, a team at Australia's RMIT University is working to invent a cost-effective and efficient way to clean everyday clothes yourself. They tried to do just that last week, publishing their findings in the journal Advanced Materials Interface. Along the way, they have found a simple and scalable way to incorporate a copper-silver base, known for its ability to absorb visible light, into the nanostructure of textiles. The team says the technology is cheap and efficient and can be scaled to industrial scale, and these attributes give it an advantage over similar self-cleaning fabric technologies. The work also paves the way for nano-reinforced textiles that can clean themselves of dirt by putting on a light bulb and wearing it in the sun. The method developed is a cost-effective and efficient method of growing special nanostructures that break down organic substances when exposed to light, just like textiles.
