Abstract

The invention discloses an electrostatic spinning preparation method of superfine high-density graphene modified polymer fibers. The electrostatic spinning preparation method uses oxidized graphene, high-density polymers, and cellulose acetate butyrate as raw materials. The electrostatic spinning preparation method has the advantages that the polymer fiber is prepared by the electrostatic spinning method, so that the difficulty in preparation of the modified fiber by the electrostatic spinning method due to difficult dissolving of polyester polymers into most of solvents is overcome; the solvent is not used, so that the environment-friendly effect is realized, and the preparation method is suitable for most of insoluble polymers and inert polymers; the preparation method is simple, the reaction time is short, the industrial degree is high, and the practical value is obvious.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an electrospinning preparation method of ultrafine high-density graphene-modified polymer fibers. Background technique [0002] Graphene, also known as single-layer graphite, refers to a two-dimensional sheet-like crystal material with a thickness of only one carbon atom that is closely arranged in a hexagonal structure of carbon atoms (honeycomb lattice). Compared with other carbon materials, graphene has a perfect large π conjugated system and the thinnest single-layer atomic thickness structure, which makes graphene have excellent and unique optical, electrical, thermal, mechanical and other physical properties and chemical properties. nature. [0003] Combining graphene and fiber materials, the new functional fiber materials constructed have excellent mechanical, flame-retardant and UV-resistant properties. At present, there are many methods for preparing graphene fibers, a...
