Not everyone can imagine that one day, instead of washing, it will be enough to hold dirty clothes in the sun or under a light bulb for a few minutes to make them absolutely clean.
A team of scientists at the Royal Institute of Technology in Melbourne (Australia) has developed an inexpensive and efficient technology for creating textiles based on nanostructures that promote the decomposition of organic substances under the influence of light.
The idea is not new. Scientists have previously worked with copper and silver nanostructured materials, which, when exposed to light, create so-called "hot electrons." By releasing energy, they force nanostructures to decompose organic matter.
So far, such structures are being created in very small quantities, and this process is quite expensive and requires high costs. The RMIT team found a way to simplify this process by growing nanostructures directly on the fabric, for which it is immersed in several special solutions for 30 minutes.
In the course of the experiments, the treated fabrics were cleaned of dirt in the light in six minutes. However, the head of the research, Dr. Rajesh Ramanathan, is in no hurry to give the technology to clothing manufacturers, apparently, rightly fearing leaving out of work a huge army of washing machine manufacturers.
