Problems solved by technology

This method generally requires three steps in the preparation process, that is, polymerization-swelling (dissolution)-hypercrosslinking, the process is complicated, and the energy consumption is large.
Moreover, the styrenic monomers that can be used for industrial production are very limited. If you want to prepare functional styrenic hypercrosslinked porous polymers, you generally need to adopt a post-modification method, which further increases the production cost.

Description

technical field [0001] The invention belongs to the technical field of new materials, in particular, the invention relates to a porous polymer material and a preparation method thereof. Background technique [0002] Porous polymer materials are widely used as catalyst supports, separation membranes, gas storage materials, and ion adsorbents. At present, porous polymer materials mainly include: (1) styrene-based hypercrosslinked porous polymers; (2) self-porous polymers; (3) polyaniline-based porous polymers; (4) conjugated porous polymers ; (5) Porous polymers based on aromatic ring coupling reactions. The preparation methods of the above porous polymer materials are relatively complicated or need to use expensive raw materials. At present, only styrene-based hypercrosslinked porous polymers have been industrialized. However, this method needs to first polymerize styrenic monomers, then dissolve or swell the styrenic polymer obtained after polymerization in a solvent, and ...
