▎ 摘　　要

NOVELTY - Preparing magnetic cross-linked chitosan/graphene composite material involves preparing magnetic chitosan nanoparticles. The prepared nanoparticles are functionally modified and then crosslinked. The cross linked product is combined with graphene to obtain magnetic cross-linked chitosan/graphene composite material. USE - Method for preparing magnetic cross-linked chitosan/graphene composite material (claimed). ADVANTAGE - The method enables to prepare magnetic cross-linked chitosan/graphene composite material which has strong mechanical property and good absorbing effect, in cost effective and eco friendly manner.
