▎ 摘  要

NOVELTY - Nanocomposite comprises 0.5-2 wt.% of graphene oxide and 0.1-2 wt.% of iron oxide, relative to total weight of chitosan polymer. USE - Nanocomposite. ADVANTAGE - The nanocomposite can be prepared with improved physical properties including tensile strength, Young's modulus and storage modulus in an economical and less labor-intensive manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) improving mechanical properties of the polymer molded product, comprises adding graphene oxide and iron oxide to chitosan polymer; and (2) preparing nanocomposite comprising preparing a mixed solution of graphene oxide, iron oxide and chitosan polymer, and preparing a molded article by drying the mixed solution into a predetermined shape.
