▎ 摘  要

NOVELTY - The preparation method of composite film involves adding kappa-carrageenan and konjac glucomannan to an aqueous solution of graphene oxide and then uniformly mixing, stirring the mixture and then placing in a glass molding machine, degassing the mixture, and drying at room temperature. USE - The method is useful for preparation of composite film, which is useful in packaging material, tissue engineering material and biological material (claimed). ADVANTAGE - The method enables simple and economical preparation of composite film with excellent biodegradability, biocompatibility, thermal stability and mechanical strength. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) composite film prepared by the method; and (2) use of composite film in packaging material, tissue engineering material and biological material.
