Abstract

The invention provides a preparation method of a non-layered molybdenum nanosheet / graphene-based fiber membrane. The preparation method comprises the following steps of preparing a pre-stripping dispersion solution of molybdenum powder, preparing a mixture of the molybdenum powder and graphene oxide, preparing a non-layered molybdenum nanosheet / graphene oxide dispersion solution and carrying out spinning and aftertreatment. According to the preparation method of the non-layered molybdenum nanosheet / graphene-based fiber membrane, the graphene oxide is added in the preparation process of a non-layered molybdenum nanosheet, the molybdenum powder can be assisted in being stripped into the non-layered molybdenum nanosheet, and the non-layered molybdenum nanosheet and the graphene oxide can be uniformly mixed. In the spinning process, the non-layered molybdenum nanosheet, graphene and the carbon black are further loaded onto a fiber, and the fiber has the advantages that the specific surfacearea is large, infrared radiation is strong, thermal conductivity is high, flexibility is good, and the bending-resistant effect is remarkable. The invention further provides the non-layered molybdenum nanosheet / graphene-based fiber membrane.

Description

technical field [0001] The present invention relates to the technical field of graphene heating devices, in particular to graphene electrospinning fiber membrane technology, and more specifically to a method for preparing a flexible non-layered molybdenum nanosheet / graphene-based fiber membrane. The non-layered molybdenum nanosheet / graphene-based fiber membrane is prepared by the preparation method of the non-layered molybdenum nanosheet / graphene-based fiber membrane. 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 it...
