Abstract

The invention discloses a preparation method of a chitosan-graphene nano medical dressing for bacterial resistance and wound healing promoting. The preparation method comprises the following steps: S1, chitosan and graphene oxide dispersion liquid obtained after acetic acid is dissolved are uniformly mixed under the ultrasonic effect, an initiator is added to react for 4 h, and thus a graphene-grafted modified chitosan solution is obtained; S2, a reducing agent is added into the graphene-grafted modified chitosan dispersion solution obtained in the step S1 to react at 80-90 DEG C, filtering under reduced pressure is conducted, and after vacuum drying, reduced graphene-chitosan functional master-batches are obtained; and S3, the reduced graphene-chitosan functional master-batches obtained in step S2, auxiliary components and an enhancer are dissolved and mixed, spinning for film forming is conducted to obtain chitosan-graphene nanofiber felt, and liquid-phase enhanced crosslinking is conducted in an acid solution to obtain the chitosan-graphene nano medical dressing for bacterial resistance and wound healing promoting. A special physical healing function can be given to a wound dressing material, and especially the effects in the aspects of physical bacterial resistance and far-infrared radiation to promote wound healing are more obvious.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a preparation method of a composite material, in particular to a preparation method of a chitosan graphene nano medical dressing for antibacterial and wound healing promotion. Background technique [0002] Wound dressing is a medical material widely used in clinical practice; as a material in direct contact with the wound surface, the wound dressing material should not only have the basic functions of absorbing the cell pus of the wound and timely hemostasis, but also require it to have good biological properties. Compatibility, antibacterial, and wound healing effects. [0003] Chitosan has a wide range of sources, good biocompatibility, and biodegradability. It is an ideal material for wound dressing. Chitosan-based wound dressings are widely used in clinical hemostasis and wound healing through drug loading modification. [0004] Electrospinning is an effective tec...
