On Feb 7, the 9th Asian Winter Games opened in Harbin, Heilongjiang province. Xinhua News Agency entered the National Advanced functional Fiber Innovation Center, focusing on the flexible carbon nanocomposite heating technology developed by the innovation center, and introducing the scientific and technological "secrets" behind the warm experience of the Asian Winter.

In the exhibition hall of the Innovation Center, the mascots Hamahama and Nini of the Asian Winter Games are displayed. Long press the button on the front of the mascots, and Hamahama and Nini will become a warm doll. The licensed scarves of the Asian Winter Games, connect the charging bank to open the switch, you can provide warm protection for the neck; A vest that can heat itself, thin and warm with a small phone app and a switch built into the pocket; Heating the steering wheel reduces the amount of electricity used to heat the trolley, allowing it to run a little farther; A cute and small hand warmer made from the image of Bing Dwen Dwen of the Beijing Winter Olympics.

These products all have one thing in common. Zhang Lin, deputy director of the Research and development department of the National Advanced Functional Fiber Innovation Center, said, "The common point of the above products is that they all use flexible carbon nanocomposite heating technology, and the core material is a film - flexible carbon nanoheating film."

Flexible carbon nanothermal film is a self-assembled conductive fiber and conductive film with high conductivity and high stability, which is developed by using carbon nanotube composite three-dimensional conductive material as continuous phase. Through the protection of two layers of fabric, and with the temperature sensor, with overcurrent, short circuit, overtemperature 3-charge protection controller and USB interface, a set of low-pressure safe heating, uniform temperature, intelligent control and machine washing heating system is formed for the flexible carbon nano heating film.

Flexible carbon nanocomposite heating technology was previously used in the Beijing Winter Olympics. During the opening and closing ceremonies of the Beijing Winter Olympic Games, we developed low-temperature wireless control components by setting large-area heating modules on seats, desktops and the ground to provide safe, efficient and scientific thermal protection for leaders and delegates. At present, the flexible carbon nanocomposite heating technology has achieved a breakthrough in the macro production of materials, forming applications in clothing, home textiles, automobiles and other fields to meet the different product needs of customers.
