▎ 摘  要

NOVELTY - The preparation method involves dispersing graphite oxide in water in a low ultrasonic vibration condition then fully mixing the graphene oxide dispersion liquid in gellan gum solution below room temperature condition to obtain hybrid nano dispersion liquid. A vacuum pump is used in filtering the hybrid nano dispersion liquid to obtain a chloroform shell-like structure layered graphene oxide nano composite film. USE - Preparation method of shell-like structure layered graphene oxide nano composite film used in field of e.g. tissue engineering, medicine. ADVANTAGE - Exhibits excellent mechanical performance and good biological compatibility by fully mixing the graphene oxide dispersion liquid in gellan gum solution. DESCRIPTION OF DRAWING(S) - The drawing shows a picture of a shell structure prepared by the layered graphene oxide nano composite film.
