Problems solved by technology

Although this method can avoid the use of templates, the solvothermal method needs to be carried out under high temperature and high pressure conditions.
Therefore, the reaction conditions are relatively harsh, and the required devices are relatively complicated, which limits its application prospects.

Abstract

The invention discloses an organic-inorganic hybridized mesoporous polymer material, which is prepared by the following steps of: dissolving a cationic surfactant into water to form a cationic surfactant aqueous solution, stirring vigorously, and adding a persulfate aqueous solution at 0-5 DEG C to form a template; stirring vigorously at 0-5 DEG C, adding a polymerized main monomer and a polymerized comonomer, blowing nitrogen for removing oxygen for 10-60 minutes, and adding an accelerant to form a reaction solution; and reacting the reaction solution in the nitrogen atmosphere at 0-5 DEG C while stirring vigorously for 12-48 hours, collecting a product, and performing vacuum drying at 40-80 DEG C for 12-48 hours. The mesoporous polymer material has the advantages of large specific surface area, the performance of organic matters and inorganic matters, realization of modification and functionalization of a mesoporous polymer, very wide application prospect, simple preparation process, wide raw material source, low raw material price and suitability for industrial production.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an organic-inorganic hybrid mesoporous polymer material. Background technique [0002] Mesoporous polymer materials with high specific surface area and pore volume have excellent performance and great application prospects in the fields of catalyst loading, drug delivery, removal of small molecules and ionic pollutants, protein separation, and enzyme immobilization. The 21st century is an era of materials chemistry, and new materials with different physical and chemical properties are constantly required in emerging fields such as nanotechnology and bioengineering. It is difficult for materials prepared from a single constituent species to meet various needs at the same time. Organic-inorganic hybrid materials organically combine organic species and inorganic species at the molecular level, so that the material has both organic properties and inorganic properties. Th...
