Abstract

The invention discloses a preparation method, a material and an application of a porous polymer. The preparation method comprises the following steps: (1) evenly dispersing the raw material (aromatic compounds, mixtures of the aromatic compounds, polymers of the aromatic compounds and/or mixtures of the polymers) into a crosslinking agent and solvent, so as to obtain a raw material mixed solution, wherein the crosslinking agent solvent is one or more of alkane dihalides; (2) adding a catalyst, carrying out Friedel-Craft reaction, and carrying out super-crosslinking, so as to obtain a crude product; and (3) washing and extracting a filter cake which is obtained after the coarse product is filtered, removing a catalyst, and drying, so as to obtain a porous polymer. The preparation method disclosed by the invention is simple in process, uses easily available raw materials, the prepared porous polymer is adjustable in pore size and specific surface area, has low cost and good adaptability, and can be used as a catalyst carrier, a separation membrane, a gas storage material or an ion adsorbing material, especially, can be used as materials for storing hydrogen and capturing carbon dioxide or methane storage materials.

Description

technical field [0001] The invention belongs to the field of polymer materials, and more specifically relates to a preparation method, material and application of a porous polymer. Background technique [0002] In recent years, organic porous polymer materials (microporous organic polymers, MOPs) have been widely used in the fields of adsorption and separation, heterogeneous catalysis, gas storage, photoelectricity, drug release, biosensing, etc., and have received great attention from researchers at home and abroad. big concern. Compared with traditional activated carbon-like and zeolite-like porous materials, MOPs show advantages such as high specific surface area, high chemical and physical stability, low framework density and diverse synthesis. From the synthesis method, MOPs can be mainly divided into: Polymers of Intrinsic Microporosity (PIMs), Covalent-Organic Frameworks (COFs), Conjugated Microporous Polymers (Conjugated Microporous Polymers). , CMPs) and hypercros...
