No, it is graphene black technology. In 2004, Andre Geim and Konstantin Novoselov, two scientists from the University of Manchester, found it. They used a special tape to split the graphite sheet in two, and finally successfully separated a single layer of graphene from the graphite. Therefore, the two scientists won the 20 10 Nobel Prize in physics. If the transparent substrate supporting a single layer of graphene material is used in the water-filled graphene brightening and rejuvenation instrument, the carbon atoms of the graphene electrothermal film will vibrate and collide when the two sections are electrified, generating heat energy, which will be radiated by far infrared energy with a wavelength of 5~ 15 micron. If graphene black technology is used in the water-spike graphene brightening and rejuvenating instrument, the heat will be uniform after power-on. You can verify it.
