▎ 摘　　要

NOVELTY - Preparing reinforcing ternary composite film using hydrogen bond network and magnetic nanoparticle comprises (i) adding aqueous solution of graphene oxide to aqueous polymer solution and stirring to obtain graphene oxide-polymer dispersion; (ii) adding magnetic nanoparticle aqueous solution having a particle diameter of 20-100 nm into the graphene oxide-polymer dispersion, and stirring to obtain dispersed oxidation graphene-polymer-magnetic nanoparticle dispersion; and (iii) forming the graphene oxide-polymer-magnetic nanoparticle dispersion into a film by spray coating assembly. USE - The diagram shows a schematic representation of the preparing reinforcing ternary composite film using hydrogen bond network and magnetic nanoparticle. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for ternary composite film reinforced by hydrogen bonding network and magnetic nanoparticle prepared has tensile stress and toughness of 303 MPa and 10.28 MJ/m3 respectively.
