On the day of the closing ceremony of the Beijing Winter Olympics, the temperature was as low as minus 2 °C, but the guests in the "Bird's Nest" viewing platform did not feel cold. The reason is the use of a new graphene technology, which is also the first time that graphene technology has been applied to The Olympic venues to achieve temperature control management.
It is understood that the interior of the auditorium chair, table and guest area sofa of the National Stadium is embedded with a new graphene flexible heating fabric material, which can achieve temperature control by simply touching the button. Graphene technology is also used in the carpet of the viewing platform. This graphene intelligent temperature control system can maintain the surface temperature of the carpet at 20 ° C in the cold outdoor.

Graphene is a new type of material with the best electrical and thermal conductivity, and the electrothermal conversion efficiency is more than 90%. After energizing, the electrical energy can be efficiently converted into heat energy, and the heat energy is radiated evenly outward, which is the closest way to the sunlight to generate heat.
According to technology supplier Beijing Innovation Aishangjia Technology Co., Ltd., the graphene material applied at the National Stadium is made of graphene and carbon nanotube dispersion, like a cloth capable of heating. Traditional thermal conductive materials such as wires, wires, and heating films lack comfort. Graphene materials have the same comfortable touch as ordinary fabrics. Through the three-dimensional arrangement combination of graphene heating fabrics, a three-dimensional far-infrared heat radiation network is constructed, which is accurately transmitted to the human body and effectively improves the somatosensory comfort.

Graphene material can also be repeatedly washed, kneaded and cut like ordinary cloth, safe and efficient. Only 24V of low-voltage DC power can be driven, and it can be stable in rain and snow. The electric conversion efficiency is also very high, and the power demand of the entire "Bird's Nest" viewing platform is only 0.098% of the overall power load of the Bird's Nest.
