“A team of materials scientists at Harvard University and the University of Exeter, UK, have invented a new fiber that changes color when stretched. Inspired by nature, the researchers identified and replicated the unique structural elements that create the bright iridescent blue color of a tropical plants fruit. The multilayered fiber, described January 28 in the journal Advanced Materials, could lend itself to the creation of smart fabrics that visibly react to heat or pressure.”Our new fiber is based on a structure we found in nature, and through clever engineering weve taken its capabilities a step further,” says lead author Mathias Kolle, a postdoctoral fellow at the Harvard School of Engineering and Applied Sciences SEAS. “The plant, of course, cannot change color. By combining its structure with an elastic material, however, weve created an artificial version that passes through a full rainbow of colors as its stretched.”…..

Smart textiles survive the spin cycle

New ‘smart’ fibres could be woven into your clothes to give them special properties, such as the ability to clean themselves, or recharge your mp3 player. It’s the fist time these kinds of fibres have been designed to survive washing at high temperatures. “Until now, such multifunctional applications have been limited by the ability to spin important materials into yarns and make sure they stay there even after washing,” says Ray Baughman of the Alan G. MacDiarmid NanoTech Institute at the University of Texas in Dallas.

 

To solve this problem, his team set about making a yarn that could be peppered with “guest” particles of interest – titanium dioxide to create self-cleaning fabrics, for instance – and hold onto them through a hot dunking in detergent.To find out more about this technology, you can read the full news story via the link below  -from the New Scientist –
