▎ 摘　　要

NOVELTY - A graphene is added into sodium algae acid solution, graphene is processed through amination under catalysis of dicyclohexylcarbodiimide and chemically reacted. The alkene/algae spinning solution is processed through coagulating bath for preparing alkene/algae as-spun fiber or alkene-algae as-spun fiber, alkene/algae as-spun fiber or alkene-algae as-spun fiber are processed through pre-heating bath and drafting bath, drafted and mold and oil is applied, to obtain graphene-functionalized alginate fiber. USE - Preparation of graphene-functionalized alginate fiber. ADVANTAGE - The method efficiently provides graphene-functionalized alginate fiber with excellent tensile strength, biocompatibility, elasticity, antistatic property and antibacterial property. DETAILED DESCRIPTION - A graphene is added into sodium algae acid solution for preparing graphene non-covalent functionalized marine algae spinning solution, graphene is processed through amination under catalysis of dicyclohexylcarbodiimide and chemically reacted for combining with sodium alga acid in a covalent for preparing graphene covalent functionalized marine algae spinning solution. The alkene/algae spinning solution is processed through coagulating bath for preparing alkene/algae as-spun fiber or alkene-algae as-spun fiber, alkene/algae as-spun fiber or alkene-algae as-spun fiber are processed through pre-heating bath and drafting bath, drafted and mold and oil is applied, to obtain graphene-functionalized alginate fiber.
