  • Alkyl chitosan-graphene oxide composite sponge and preparation method and application thereof
    Patent number: 11123452
    Abstract: The present invention relates to an alkyl chitosan-graphene oxide composite sponge and preparation method and application thereof. The alkyl chitosan-graphene oxide composite sponge provided by the present invention includes alkyl chitosan and graphene oxide absorbed on the alkyl chitosan, and the adsorbing capacity of the graphene oxide is 3-28 wt. %. In the present invention, alkyl chitosan is used as a matrix to combine graphene oxide and alkyl chitosan; the obtained composite sponge has excellent hemostatic performance and blood absorption capacity. Results of embodiments indicate that the in-vitro whole blood coagulation time is less than 58 s, the hemostasis time of a rabbit femoral artery hemorrhage model is less than 155 s, the hemorrhage mass is less than 5.4 g, and the hemostatic effect is superior to a pure alkyl chitosan sponge or graphene oxide powder when the composite sponge provided by the present invention is used for hemostasis.
