▎ 摘 要
NOVELTY - Method for preparing a graphene oxide-modified medical absorbent cotton, involves (a) sequentially adding a cotton fiber solution and a large-sheet graphene oxide solution to a container, ultrasonically processing, and uniformly stirring and mixing, (b) after stirring, adding a medium-sheet graphene oxide sheet aqueous solution, and continuously stirring and mixing uniformly, (c) dripping a Tris solution into the container to adjust the pH of the reaction system solution to alkaline, then adding a crosslinking agent and a dispersant to the reaction system solution, and uniformly stirring and mixing, (d) freeze-drying the obtained solution, and (e) sterilizing the obtained graphene oxide absorbent cotton under sterile conditions, and packaging to obtain the finished product. USE - The method is useful for preparing a graphene oxide-modified medical absorbent cotton (claimed), which is useful in the surgical hemostasis field. ADVANTAGE - The graphene oxide modified absorbent cotton has a loose and porous structure, so it has excellent water absorption and hemostasis effects and mechanical strength, does not increase the infection probability, does not affect tissue healing, and is cheap. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the graphene oxide-modified medical absorbent cotton prepared by the method.
