▎ 摘  要

NOVELTY - Post-synthesis modified covalent organic frameworks (COFs) material with sodium-ion battery performance, is claimed. The material structure is synthesis of monomers containing more highly active functional groups, and more active sites and pore structures exposed by its characteristic nanosheet structure, and part of the C=S highly active functional groups formed due to sulfur modification. USE - The post-synthesis modified COFs material with sodium-ion battery performance is useful for functional treatment of porous structure. ADVANTAGE - The traditional synthesis process, is easier to form two-dimensional COFs nanosheets with better electrochemical properties, the post-synthesis modification treatment does not damage the original COFs framework structure, can effectively maintain its porous structure, which expands ideas for the development of polymer electrode materials.
