Abstract
A graphene electronic heating device and a preparation method thereof are provided. The graphene electronic heating device includes a graphene layer, which is used as a heat source for fully heating a to-be-combusted substance in an accommodating cavity, a Teflon layer and a ceramic layer, which are arranged for realizing that the to-be-combusted substance can be continuously and stably combusted in the accommodating cavity without peculiar smell diffusion, and meanwhile increasing the endurance time of the graphene electronic heating device under the equal energy storage; the preparation method has simple process, convenient process control and stable product quality, and facilitates to large-scale production.
