Nano Express reported that the National Graphene Institute of the University of Manchester, UK( NGI@UoM )Scientists have utilized the extraordinary thermal properties and flexibility of graphene to create an intelligent adaptive garment and demonstrated its dynamic thermal radiation control effect. This achievement also lays the foundation for new applications in interactive infrared display technology, covert infrared communication technology, and other areas.
The radiation energy from the human body is expressed in the form of electromagnetic waves and belongs to the infrared spectrum (blackbody radiation). In hot climates, infrared transparent textiles can be used to reduce
Low body temperature; When insulation is needed, fabrics based on the principle of infrared shielding can reduce the heat loss of the body.
In 2004, the University of Manchester first separated graphene with single atomic thickness and explored its properties. The potential uses of this material are very broad
Pan. With the deepening of research, atomic level graphene has been commercialized and promoted in fields such as batteries, mobile phones, and automobiles. In the NGI scientist project, they utilized
The thermal radiation on the surface of textiles was controlled using a graphene layer.
Professor Coskun Kocabas, the project leader, said, "The control of thermal radiation is very necessary for certain key applications, such as cooling and low temperature in hot climates."
Insulation under temperature conditions. The potential application directions of new technologies include infrared displays, infrared communication, and adaptive packages.
Previously, the Kocabas team used graphene to create thermal camouflage suits that could "deceive" infrared cameras. Based on this, new technologies not only enable thermal radiation control
It is more intelligent and can be integrated with current cotton spinning technology.
To confirm this, researchers developed a prototype product lined with a T-shirt. This product allows the wearer to send messages that are invisible to the naked eye, but infrared cameras can
Read the encoding information.
Professor Kocabas said, "We have demonstrated the possibility of transforming the unique optical properties of graphene into new technologies. It demonstrates properties that conventional materials do not possess."
Can. In the next stage, we hope that this technology can be used to solve the dynamic thermal management problem of Earth orbit satellites. Orbiting satellites will experience
The test of extreme high temperatures, and freezing in the shadow of the Earth. Our technology can adjust satellite temperature by controlling thermal radiation to achieve on-demand dynamic heat pipes
"Li."
Professor Kostya Novoselov, a researcher, added, "This magical adaptive effect essentially stems from the unique band structure of graphene. It can be seen that it gives birth to High tech applications are very exciting
