New nano fabrics can both charge and prevent disease

Release date: 2015-08-07




Recently, Cornell University's Textile Nanotechnology Laboratory has created a new type of fabric that can sterilize, conduct electricity, prevent helium, adsorb harmful gases, and splicing transistors into shirts and dresses. “In the nanoworld, we can control cellulose-based materials at the atomic level,” says Estrozza, a laboratory principal and associate professor of fiber science at Cornell University. Today, the team has made cotton fibers into electronic components, such as transistors and thermistors, so unlike the addition of electronic components to fibers, researchers have made fibers directly into electronic components.

"This topic uses carbon fiber to make transistors and other components, bringing a new perspective to the seamless connection of electronics and textiles, thus making it possible to create unique wearable electronic devices." Estroza said . Using the irregular morphology of cotton, researchers added conformal coatings containing nano-gold particles and semi-conductive and conductive polymers to natural cotton fibers to adjust their properties.

Not only that, but the researchers also used conductive cotton to make clothes that can charge iPhones: cut ultra-thin solar panels into appropriate shapes and bury USB charging sockets at the waist, and the clothes that are excited in the southwest can Capture enough sunlight to charge your phone and other handheld devices.

This technology can be embedded in a shirt to measure heart rate and analyze sweat, sewn into a pillow to detect brain signals, or applied to interactive textile products with heating and cooling capabilities.

In addition, by synthesizing nanoparticles and attaching them to cotton, not only can the surface be colored without dyes, but the new surface can kill 99.9% of the bacteria, which can be used to prevent colds, flu and other diseases. .

Two students at Estroza used metal-organic skeleton molecules to create a hooded tights to protect against mosquitoes carrying malaria. Other students have also used metal-organic skeletons to make masks and headscarves that capture toxic gases in specific ways.

“We want to use the power of these molecules to absorb the gas and mix the metal organic framework into the fiber, so that we can create a very efficient filtration system.” Estroza explained that they often look for cotton. A new method of canvas to make it have unlimited modern uses.
