Description
Technical Field
The invention belongs to the field of porous polymer materials, and relates to a super-crosslinked porous polymer fiber and a preparation method thereof.
Background
The hypercrosslinked polymer is a porous polymer material with a bridging network structure formed by rigid aromatic monomers through a friedel-crafts alkylation reaction, has the advantages of light weight, controllable pore structure, large specific surface area, good thermal stability, chemical stability and the like, and is widely applied to the fields of water treatment, heterogeneous catalysis, gas adsorption and separation and the like. The super-crosslinked polymer fiber has a one-dimensional structure different from that of a granular material, is easy to assemble into a three-dimensional network by overlapping and winding, has remarkably enhanced mechanical properties, and has more obvious advantages in the application process. Therefore, the development of a synthetic method of the super-crosslinked polymer fiber has important significance for preparing a high-performance porous polymer material.
The synthesis strategy of the super-crosslinked polymer fiber is mainly a template method, and usually comprises the steps of adding a template agent into a reaction system, and polymerizing an aromatic small-molecular monomer on the surface of the template agent to form a fiber structure (Polym. chem.2019,10,4239; ACS appl. Mater. interfaces 2017,9, 20779). Or a bottle brush-shaped copolymer precursor is prepared by an organic synthesis means, a main chain of the precursor is used as a template, and a large number of aromatic rings of a side chain of the precursor are woven under the action of an external cross-linking agent to form a hypercrosslinked structure, so that hypercrosslinked polymer fibers are obtained. At present, reports of synthesizing the super-crosslinked polymer fiber by a simple one-step method by using aromatic macromolecules as monomers are not found, and the invention is expected to further enrich the synthetic method of the super-crosslinked polymer fiber.
