New Material: The "Secret" Of Science And Technology Behind The Warmth Experience Of The Asian Winter Games

　　 On February 7, the 9th Asian Winter Games opened in Harbin, Heilongjiang Province. Xinhua News Agency walked into the National Advanced Functional Fiber Innovation Center and focused on the flexible carbon nano composite heating technology developed by the innovation center to introduce to you Asian Winter Games The "secret" of technology behind the thermal experience. ?

　　 In the exhibition hall of the Innovation Center Asian Winter Games The mascots of Binbin and Nini, long press the button on the mascot's chest, Binbin and Nini will become a warm doll; The scarf, a licensed product of the Asian Winter Games, can provide warm protection for the neck by connecting the power bank and turning on the switch; A self heating vest, which can be thin and warm through mobile phone applet and pocket built-in switch; Heating the steering wheel can reduce the power consumption of the tram for heating, so that the tram can run farther; The hand warming treasure made from the image of ice pier of Beijing Winter Olympics is cute and small. ?

　　 These products all have a "common feature". National Advanced Functional Fiber Innovation Center Zhang Lin, vice director of R&D Department, said, "The common point of the above products is that they all use flexible carbon nano composite heating technology, and the core material is a film - flexible carbon nano heating film." ?

　　 The flexible carbon nano heating film is a three-dimensional composite of carbon nanotubes Conductive material Self assembled conductive fiber with high conductivity and high stability developed for continuous phase and Conductive film . Protected by two layers of fabric Temperature sensor The controller and USB interface with overcurrent, short circuit and over temperature three charge protection form a set of low-voltage safe heating, uniform temperature, intelligent control and machine washing heating system for the flexible carbon nano heating film. ?

　　 The flexible carbon nano composite heating technology has been applied to the Beijing Winter Olympic Games earlier. During the opening and closing ceremonies of the Beijing Winter Olympic Games, a large area of heating modules were set up on the seats, desks and ground, and low-temperature wireless control elements were developed to provide safe, efficient and scientific thermal support for leaders and representatives attending the Games. At present, the flexible carbon nano composite heating technology has achieved a breakthrough in macro quantitative production of materials, and has formed applications in clothing, home textiles, automobiles and other fields to meet customers' different product needs. ?
