NOVELTY - A chitosan/graphene oxide composite biological scaffold material preparing method involves dissolving chitosan in acetic acid and stirring to obtain a chitosan solution, adding natural graphite, sodium nitrate, concentrated sulfuric acid, potassium permanganate, distilled water and hydrogen peroxide centrifuging and freeze-drying to obtain graphene oxide powder, re-dispersing redox oxide powder in deionized water, adding a graphene oxide dispersion to the chitosan solution to obtain a uniform dispersion of chitosan oxide graphene, placing the copper column in a container containing liquid nitrogen, placing dispersion to the mold in the copper column and drying to obtain the finished product. USE - Method for preparing chitosan/graphene oxide composite biological scaffold material.
