What happens when graphene heats up?

Graphene heat generation is based on the characteristics of single-layer graphene.

First of all, graphene is the material with the highest thermal conductivity so far and has very good thermal conductivity. Secondly, the carrier (conducting ion) of graphene at room temperature is 15,000cm/(V.s), which is more than ten times that of silicon and more than twice that of indium antimonide (InSb). Indium antimonide is currently the largest Know the substance with the highest carrier mobility.

Graphene heating film, like conventional heating film, needs to be powered on. When the electrodes at both ends of the graphene heating film are energized, the carbon molecules in the film produce phonons, ions and electrons in the resistance, and the generated carbon molecules collide with each other (also called Brownian motion) to generate heat energy. Radiates heat evenly in a planar manner by controlling far-infrared rays with wavelengths between 5 and 14 microns.

The total effective electric heating energy conversion rate reaches more than 99%, coupled with the superconductivity of the special graphene material, ensuring stable heating performance. But unlike traditional silk heating films, it is stable and safe, and the infrared it emits is called the "light of life."

The role of graphene:

The discovery of graphene, and the subsequent discovery of many excellent properties, has brought new hope to a wide range of industrial fields: fast-charging batteries, super storage Capacitors, anti-corrosion coatings, industrial catalysts, electronic components and other industries.

Many leading graphene research companies have greatly improved the performance of traditional products through research on graphene materials, thereby establishing higher technical barriers to the industry and promoting industrial upgrading.

From a global perspective, graphene is still in the research and development stage, and countries are still in the patent layout stage for this emerging material. The trend of industrialization has not yet emerged, and the entire industrial chain has not yet been formed.

However, competition in the graphene field has always been very fierce, and no one hopes to seize the opportunity and occupy the commanding heights of the industry as soon as possible. At present, graphene is widely used in seawater filtration, anti-corrosion coatings, energy storage batteries, graphene heating films and other fields.

Graphene heating film is closer to our lives and is often used in physical therapy protection, mural heating, and whole-home heating. The editor below will introduce to you the heating principle of graphene heating film, which is closely related to our lives.
