Conductive Nano Coating Textile And Clothing Textiles

Imagine inserting a USB port into a piece of paper and turning it into a tablet computer.

It may take a while, but the researchers at North Carolina State University have studied how to apply conductive nano coating to simple textiles, such as

Woven cotton cloth

Or even a piece of paper.

"Usually conductive nano coating is applied to

Inorganic materials

Such as silicon.

If we can find a way to apply them to textiles (cheap, flexible materials, surface textures), this will mean a cost-effective approach, which is a framework for improving current and future electronic devices.

"JesseJur, a leading author of the paper, is an assistant doctor in textile engineering, chemistry and science.

The so-called atomic layer deposition inorganic material coating technology, commonly used in solar cells, sensors and

Microelectronic technology

The researchers envisaged the application of this technology on the surface of textiles, such as shuttle cotton and non-woven polypropylene surfaces, and the same materials for reusable grocery bags.

"Imagine that the coated fabric, each of which has the same nano thickness coating, is thousands of times more thinner than human hair, which can be achieved by atomic layer deposition technology," Jur said.

The study was carried out in his laboratory by Akcoa, Professor of chemistry and Biomolecular Engineering in North Carolina, and the results showed that ordinary textile materials were used to make complex electronic devices. GregoryParson

As part of their research, researchers have created a program to quantify the electrical conductivity of conductive materials for textile materials.

At present, the standard of measuring conductivity is using a four point probe, putting an ammeter between the two probes, and putting a voltmeter between the other two probes.

However, these probes are too small to measure the readings of textile materials accurately.

In the paper, the researchers said that they used new technology to make accurate measurements with larger probes.

Electrical conductivity.

This new system allows researchers to better understand how to turn the coating on textiles into conductive devices.

"We do not expect to use cotton to make complex pistors, but simple electronic devices can benefit from the flexibility of textile materials," explains Jur.

"Research like this has potential health and testing applications, because we may have embedded sensors in real materials at first, which can track heart rate, body temperature, exercise and more real-time tracking.

To do this, you must attach a wire harness to the entire fabric, which makes the fabric large and uncomfortable.

In the electronic world, ideals are always smaller and lighter.

If we can improve how to apply and measure the conductive coating on textiles, we may move the needle and coating equipment of the coating equipment with essential electrical conductivity, and also have all the benefits of natural textile materials for human beings.

The paper was published in the June new functional material version.

The research is funded by the Department of energy and the nonwovens cooperative research center.
