Nanotechnology-based self-cleaning fabrics
February 20th, 2008

A recent American Chemical Society’s Weekly PressPac briefly describes how Australian researchers have used nanotechnology to develop ‘self-cleaning’ wool and silk fabrics. The researchers ‘prepared wool fabrics with and without a nanoparticle coating composed of anatase titanium dioxide, a substance that is known to destroy stains, dirt, and harmful microorganisms upon exposure to sunlight.’ In one of their experiments, they poured red wine upon pristine and nanotechnology-coated wool. After 20 hours, their coated fabric ‘showed almost no signs of the red stain, whereas the untreated fabric remained deeply stained.’ The researchers think these fabrics could become available in a near future.
