| titleOfInvention | Preparation method of hierarchical pore chitin material |
| abstract | The invention relates to a preparation method of a porous chitin material, belonging to the technical field of materials. The invention adopts natural polysaccharide chitin as a material substrate, calcium carbonate and chitosan are respectively used as a super-macroporous template and a microporous-mesoporous template, and the template is removed by acid treatment after the three are mixed and formed, so that the hierarchical porous chitin material is finally obtained. The chitin material prepared by the preparation method has the structure of ultra-large pores, mesopores and micropores, wherein the mesopores and the micropores can provide larger surface area, and the ultra-large pores and the macropores can promote the medium to rapidly enter the inner pore passage of the chitin material, promote mass transfer and improve efficiency. Meanwhile, the method has the advantages of simple process, easy industrial production, wide raw material source, easy degradation, no toxicity, good biocompatibility and huge application potential in the fields of separation, catalysis, medicine, energy and the like. |
