Yes. Graphene has very good thermal conductivity properties. The thermal conductivity of pure defect-free single-layer graphene is as high as 5300W/mK. It is the carbon material with the highest thermal conductivity so far. Its thermal conductivity is higher than single-walled carbon nanotubes (3500W/mK) and multi-walled carbon nanotubes (3000W). /mK).
When it is used as a carrier, the thermal conductivity can also reach 600W/mK. In addition, the ballistic thermal conductivity of graphene can lower the lower limit of the ballistic thermal conductivity of carbon nanotubes per unit circumference and length.
The structure of graphene is very stable, with a carbon-carbon bond of only 1.42. The connections between carbon atoms inside graphene are very flexible. When external force is applied to graphene, the carbon atom faces will bend and deform, so that the carbon atoms do not have to be rearranged to adapt to the external force, thereby maintaining structural stability. This stable lattice structure gives graphene excellent thermal conductivity. In addition, when electrons in graphene move in orbits, they are not scattered by lattice defects or the introduction of foreign atoms.

Characteristics of graphene floor heating:
1. Comfortable and healthy. The temperature of floor heating is from bottom to top, giving people a comfortable feeling of warm feet and cool head, which is in line with the theory of traditional Chinese medicine. The heat is mainly transferred in the form of radiation, which does not dry the air. The wavelength of the radiation is far infrared of 8-12 microns, which is beneficial to the human body.
2. Energy saving and environmental protection. To achieve the same room temperature effect, it can be adjusted 2-3 degrees lower than traditional heating, effectively saving energy. And it will not pollute the indoor air.
3. Even and stable heat dissipation. Since floor heating transmits heat through concrete, the heat is distributed evenly. In addition, concrete has an energy storage effect, so the room temperature can be kept stable even if heating is intermittent.
4. Reduce floor noise. Floor slabs in China generally use prefabricated panels or cast-in-place panels. The sound insulation effect is very poor. People walking upstairs will affect the downstairs. Floor heating is used to increase the insulation layer, which has a very good sound insulation effect and can reduce noise pollution; the floor heating process is silent. Silent, the indoor environment is quiet and there is no air conditioning noise, which helps children focus on learning, thereby improving learning efficiency.
