| titleOfInvention | Graphene composite pellet with radial multistage pore structure and preparation method and application thereof |
| abstract | The invention discloses a graphene composite pellet with a radial hierarchical pore structure and a preparation method and application thereof. The preparation process comprises the following steps: 1) uniformly dispersing graphene oxide in a polymer aqueous solution to obtain a uniform suspension; 2) dripping the graphene oxide suspension into a receiving liquid controlled by a low-temperature freezing bath to obtain composite crystallized pellets; 3) freeze-drying the obtained crystallized composite pellets to obtain graphene oxide/polymer pellets; 4) adding the obtained graphene oxide composite pellets into a cross-linking agent solution for cross-linking so as to improve the strength of the pellets; 5) and carrying out liquid phase or gas phase reduction on the crosslinked composite pellets. The graphene composite pellet prepared by the invention not only has certain mechanical strength, but also has a multi-level pore structure of micropores, mesopores and macropores, is beneficial to the diffusion of adsorbed substances during adsorption, has good adsorption performance on small, medium and macromolecular substances and certain viruses, and is expected to be used as an adsorbent in blood perfusion therapy. |
