Polymer composite material with hemostasis and anti-adhesion properties and preparation method and application thereof

The invention belongs to the technical field of high polymer materials and medical treatment, and particularly relates to a polymer composite material with hemostasis and anti-adhesion properties and a preparation method and application thereof. The system of the composite material is formed by an amphipathy segmented copolymer, a solvent taking water as a main part, and a hemostatic drug jointly; the polymer composite material can be subject to thermotropic gelation phase transformation along with high temperature, is in a solution state when temperature is lower than sol-gel transformation temperature, and spontaneously forms gel when the temperature is higher than the sol-gel transformation temperature, and this process is reversible; a solution system has thermosensitivity property and can spontaneously form the gel under body temperature; after being coated on a postoperative wound face, the material solution has hemostasis and anti-wound-face-adhesion effects.
