Abstract

The invention relates to a preparation method of a graphene nonwoven fabric, wherein the preparation method includes the steps: step 1, preparing a solution with a concentration of 25%-65% from a polymeric monomer with deionized water, adding a dispersant and a pore-forming agent, and stirring for 5-30 min; step 2, adding a graphene powder into the solution of the step 1, carrying out ultrasonic dispersion to obtain a graphene suspension mixed liquid A; step 3, heating the graphene suspension mixed liquid up to 42-85 DEG C, then adding a crosslinking agent, and carrying out ultrasonic dispersion to form a graphene suspension mixed liquid B; step 4, evenly spraying a surface layer of a nonwoven fabric base material with the graphene suspension B in turn by a sprayer; step 5, making an initiator into a solution, evenly spraying the surface layer of the nonwoven fabric base material with the initiator by a double-atomizing device, initiating crosslinking polymerization and pore-forming, and thus obtaining a graphene nonwoven fabric; and step 6, placing the graphene nonwoven fabric in a baking oven, and carrying out drying treatment to obtain the graphene nonwoven fabric.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary materials, in particular to a preparation method of a graphene nonwoven fabric. Background technique [0002] Graphene refers to a single layer of carbon atoms tightly packed into a two-dimensional honeycomb structure, which is the basic unit for constructing other dimensional carbon materials (such as zero-dimensional fullerenes, one-dimensional carbon nanotubes, and three-dimensional graphite). Single-layer graphene has a large specific surface area, excellent electrical and thermal conductivity and low thermal expansion coefficient. In particular, its high conductivity, large specific surface properties and its monolayer two-dimensional nanoscale structural properties can be used as electrode materials in bipolar plates of fuel cells, supercapacitors and lithium-ion batteries. [0003] In addition, researchers have found that graphene has certain antibacterial properties in previou...
