▎ 摘　　要

NOVELTY - Preparation of graphene heating body with adjustable wide band heat radiation emissivity comprises generating graphene under the laser irradiation by the carbon-containing substrate, under a certain voltage, graphene by electric heating conversion heating and releasing heat radiation, by further adjusting the laser parameter to make the graphene heated body surface generate periodic fold, using the interference caused by wrinkle to top part the control of the infrared emission rate, obtaining the graphite heating body. USE - Preparation method of graphene heating body with adjustable wide band heat radiation emissivity used in wearable infrared therapeutic apparatus for treating arthritis, lumbar muscle strain, muscle swelling and other diseases. ADVANTAGE - The graphene heating body prepared by the method can realize accurate control of wide band heat radiation emission rate, which can be applied to multiple technical field, especially suitable for wearable infrared therapeutic instrument series medical appliance field. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the graphene heating body.
