Abstract

The invention provides a palladium nanosheetgraphene-based heating film, which comprises a first transparent insulating layer, an electrode, a second transparent insulating layer and a palladium nanosheetgraphene-based fiber membrane, wherein the first transparent insulating layer covers one surface of the palladium nanosheetgraphene-based fiber membrane, the second transparent insulating layer covers the other surface of the palladium nanosheetgraphene-based fiber membrane, one end of the electrode is electrically connected with the palladium nanosheetgraphene-based fiber membrane, and the other end of the electrode extends out of the first transparent insulating layer or the second transparent insulating layer. According to the palladium nanosheetgraphene-based heating film disclosed bythe invention, by virtue of the high-efficiency photo-thermal conversion efficiency and electro-thermal conversion efficiency of the palladium nanosheetgraphene-based fiber film, the electric heatingand photo-thermal diversified heat production functions are realized.

Description

technical field [0001] The invention relates to the technical field of graphene heating devices, in particular to a flexible palladium nanosheet / graphene-based heating film. Background technique [0002] Graphene is a two-dimensional nanomaterial with a hexagonal honeycomb lattice structure formed by carbon atoms through sp2 hybrid orbitals and only one layer of carbon atoms thick. The unique structure of graphene endows it with many excellent properties, such as high theoretical specific surface area (2630m 2 / g), ultra-high electron mobility (~200000cm2 / v.s), high thermal conductivity (5300W / m.K), high Young's modulus (1.0TPa) and high light transmittance (~97.7%), etc. With its structure and performance advantages, graphene has great application prospects in energy storage and conversion devices, nanoelectronic devices, multifunctional sensors, flexible and wearable electronics, electromagnetic shielding, anti-corrosion and other fields. In view of the flexibility and c...
