titleOfInvention | Preparation method of porous polymer |
abstract | The invention belongs to the technical field of chemical industry, and particularly discloses a preparation method of a porous polymer for adsorbing hydrogen. The method comprises the following steps: a) weighing melamine and an aprotic polar solvent, mixing, stirring, dissolving, adding an MDI tripolymer (namely 4,4'-diphenyl-methane-diisocyanate tripolymer), reacting at 150-190 DEG C for 18-36 hours, carrying out suction filtration, washing a sample with acetone, and drying to obtain an intermediate product; and b) putting the intermediate product into a solvent, and refluxing at 40-80 DEG C for 10-15 hours, so as to obtain the porous polymer. The method disclosed by the invention has the advantages of low cost of raw materials for preparing a hydrogen storage material, simple process and short time; the technological conditions are easy to control; the prepared porous polymer can adsorb a great amount of hydrogen under high pressure; through detection, the specific surface area of the porous polymer can be up to 270m<2>/g; the micropore volume accounts for 12%-20% of total pore volume; when the maximal constant volume pressure is 7MPa, the adsorbing capacity of the porous polymer prepared by the method on hydrogen can be up to 8wt%; and the hydrogen storage capacity is high. |
