[Beijing Winter Olympics] "Putting on" high-tech graphene makes the Beijing Winter Olympics not afraid of severe cold

  [Commentary] The Beijing Winter Olympics are underway. In addition to exciting events, technological elements have also become a highlight.

They are not only reflected in the competition facilities and epidemic prevention equipment, but also in all aspects of people's clothing, food, housing and transportation.

The application of graphene technology is found in the clothing worn by the stadium personnel.

  [Explanation] According to reports, graphene is currently the material with the highest thermal conductivity. In the clothes, scarves, socks, gloves and other clothing worn by relevant personnel in the Beijing Winter Olympics, graphene textile flexible heating materials are used.

  From the physical point of view of this material, it is like an ordinary cloth. We make graphene into an aqueous dispersion, and deposit the aqueous dispersion into a cloth-like structure similar to fibers in a special way. , so this material is very soft, breathable, washable, and safe, you can cut it with scissors without any problem, and it can work normally even if soaked in water during use.

  [Commentary] Chen Lijun pointed to a graphene heating vest on his body and said that the temperature of the Beijing Winter Olympics sports venues can reach as low as -30 ℃. Wearing clothes with graphene heating materials can quickly heat up and help staff resist the cold .

  Look at this small button on my chest. In fact, it is a complete control device for this suit. When you touch the button, the light turns on, and the suit starts. It can quickly make the suit arrive in a low temperature environment. The temperature of 55 ℃, and then 45 ℃ and 35 ℃ to adjust by yourself, so that our volunteers, athletes, spectators and staff can quickly restore the temperature of the human body in a low temperature environment, and play the role of cold resistance and warmth.

  [Explanation] In addition to clothes for people to wear, "cloud broadcast technology" also "wears" graphene.

The researchers made a cloud broadcast backpack using graphene flexible heating fabric material, which can instantly generate a temperature rise of 50 °C, even in a low temperature environment of -20 °C, the equipment is not afraid of challenges.

  [Explanation] The Winter Olympics is not a "one-shot deal". Chen Lijun said that a series of new technologies and new products applied at the Beijing Winter Olympics will not only lay a solid foundation for promoting the sustainable development of ice and snow sports in the future, but also lay a solid foundation for the next step in Beijing. Provide impetus to build an international science and technology innovation center.

  In fact, the precipitation of our Winter Olympics technology this time will actually help Beijing to build an international scientific and technological innovation center in the next step, as well as the promotion of the industrial application of core new materials in the next 14th Five-Year Plan. In fact, I think it is very helpful. .
