New nano-fabric can both charge and prevent disease

Recently, the Laboratory of Textile Nanotechnology at Cornell University in the United States has created a new type of fabric that can sterilize, conduct electricity, prevent helium, absorb harmful gases, and can weave transistors into shirts and dresses. "In the nanoworld, we can control cellulose-based materials at the atomic level," said Astrozza, an assistant professor of fiber sciences at Cornell University. Today, the team has made cotton fibers into electronic components such as transistors and thermistors, so unlike adding electronic components to fibers, researchers have made fibers directly into electronic components.

“This project uses carbon fiber to make transistors and other components, which brings a new perspective for the seamless connection of electronic products and textiles, thus providing possibilities for the creation of unique wearable electronic devices.” Astroz said . Using the irregular morphology of the cotton, the researchers added conformal coatings containing semi-conductive gold and gold particles and semi-conductive and conductive polymers to the natural cotton fibers to adjust their properties.

Not only that, the researchers also used electrically conductive cotton to make clothes that could be used to charge the iPhone: Cut ultra-thin solar panels into appropriate shapes and bury the USB charging socket in the waist. Capture enough sunlight to charge the phone and other handheld devices.

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

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

Two students of Estroza used metal-organic skeletons to create a tights hooded to protect against mosquitoes that carry malaria. Other students also use metal-organic frameworks to make masks and scarves that can trap toxic gases in a specific way.

"We want to harness the power of these molecules to absorb the gas and mix the metal organic skeleton with the fiber, so that we can create a very effective filtration system." Estroj explained that they also often look for cotton cloth The new method of canvas makes it infinitely modern.

Raw Material Of Other Chemicals

These materials are raw materials for different chemicals. One of them is possible to be used in many chemicals or fields. Different materials are also possible to used for the same finished material.



It is basic material for many fields, such as pharma, chemical, dying, washing industry, and manufacture industry. Some are powder, some granule, some flake, some crystalline.



It is identified by purity and granule/block size, purity is the main identified method. It is used in different products as per its size.
