Graphene, a revolutionary two-dimensional material composed of a single layer of carbon atoms arranged in a hexagonal lattice, has been making waves in various industries, and heating technology is no exception. But how exactly does graphene heating work?
At its core, graphene heating relies on the material's remarkable electrical and thermal conductivity properties. When an electric current passes through graphene, its atoms vibrate rapidly due to the resistance they encounter. This atomic vibration generates heat, a process known as the Joule heating effect. What sets graphene apart is its ability to convert up to 99% of electrical energy into heat, making it an incredibly efficient heating solution.
Another key advantage of graphene heating is its even heat distribution. Unlike traditional heating elements that may produce hot spots, graphene's uniform structure allows heat to spread evenly across the entire surface of the heating material. This ensures consistent warmth, enhancing both comfort and energy efficiency.

| When substances absorb far-infrared rays, the molecular motion intensifies, which is manifested as a rise in temperature, playing a role in heating and baking. |
When materials need to be solidified during the drying process, a chemical reaction is required. Suppose the frequency of far-infrared rays is the same as the vibration frequency of the active groups participating in the chemical reaction. In that case, the active groups in the macromolecules will RESOnate, accelerating the breakage of chemical bonds, increasing the number of active groups participating in the reaction, and speeding up the progress of the reaction. |
In the medical field, after infrared rays irradiate the human body, they can promote blood circulation and increase the regeneration ability of organic tissues. In agriculture, irradiating seeds with infrared rays can shorten their dormancy period and improve the germination rate of seeds. |
