▎ 摘  要

NOVELTY - Preparing graphene by peeling sodium alginate by high shearing dispersion comprises (i) dissolving sodium alginate in deionized water, adding graphite powder, dispersing uniformly in ultrasonic condition; (ii) peeling layered sheets of graphene by high shear dispersion to obtain lamellar graphene; and (iii) centrifuging lamellar graphene to remove upper layer solution and centrifuging resulting upper layer solution in deionized water, washing and freeze drying. USE - The method is useful for preparing graphene by peeling sodium alginate by high shearing dispersion (claimed). ADVANTAGE - The method of removing alginic acid functional group attached to the surface of the stripped graphene has improved thermodynamic performance of composite material.
