Abstract

The invention provides a preparation method and an application of a micro-porous polymer. The preparation method comprises the following steps: sequentially adding a monomer, an anhydrous organic solvent and an anhydrous catalyst into a dried pressure-resistant tube, performing magnetic stirring under a dark condition, and extracting ad drying the obtained crude product to obtain the micro-porouspolymer. The preparation method adopts the monomer obtained by polymerizing indanone groups or indolyl groups in order to synthesize the polymer and increases the spatial distortion of the monomer toincrease the specific surface area of the polymer in order to achieve a good gas adsorption performance, so the prepared micro-porous polymer is suitable for storing and transporting hydrogen and other gases.

Description

technical field [0001] The invention belongs to the field of microporous polymer materials, in particular to a preparation method and application of microporous polymers. Background technique [0002] Hydrogen, as a non-polluting, clean and renewable energy, has attracted widespread attention in its development and application, among which hydrogen storage technology is a key link in the development and application. At present, metal alloys are often used as hydrogen storage materials in industry. Although this material has high safety and good hydrogen storage effect, the hydrogen storage capacity per unit mass of the material is small, and the metal hydride is easy to break, and the hydrogen storage metal is easy to pulverize. Carbonaceous hydrogen storage materials have also attracted widespread attention, but the physical adsorption of hydrogen molecules on the surface of carbon materials is too weak to meet the requirements of practical applications under normal tempera...
