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.

Meanwhile, the preparation process is simple, the source of raw materials is wide and cheap, and the organic-inorganic hybridized mesoporous polymer material is suitable for industrial production.

Description

Technical field [0001] The invention belongs to the field of polymer materials, and specifically 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, small molecule and ionic pollutant removal, protein separation, and enzyme immobilization. The 21st century is the era of materials chemistry. New materials with different physical and chemical properties are constantly needed in emerging fields (such as nanotechnology and bioengineering). It is difficult for materials prepared from a single composition species to meet various needs at the same time. Organic-inorganic hybrid materials organically combine organic and inorganic species at the molecular level, so that the materials have both organic and inorganic properties. Therefore, the preparation of org...
