▎ 摘 要
NOVELTY - Preparaing white and gum-galactomannan-oxidized graphene film involves dissolving Bletilla striata gum and galactomannan in the oxidation water solution graphene stirring, dispersing after freezing, and drying at room temperature to obtain product. USE - Method for preparaing white and gum-galactomannan-oxidized graphene film used in the field of medical food packaging material, tissue engineering or biological material (claimed). ADVANTAGE - The method has high thermal stability and mechanical strength, and good biocompatibility.
