Mesoporous zeolite multilayer hemostatic gauze and preparation method thereof

The invention belongs to the technical field of biomedical materials, and particularly relates to mesoporous zeolite multilayer hemostatic gauze and a preparation method thereof. The preparation method comprises the following steps. The preparation method comprises the following steps: (1) by taking a mixed solution of chitosan and polyvinyl alcohol as a shell layer solution and a sodium alginate solution as a core layer solution, carrying out coaxial electrostatic spinning on tin foil paper to prepare a core-shell fiber layer; (2) crushing zeolite, and dispersing the crushed zeolite in ethanol to prepare a zeolite suspension; (3) uniformly dripping the suspension on the core-shell fiber layer, and drying to obtain a zeolite/electrostatic spinning core-shell fiber layer; and (4) on the basis of the zeolite/electrostatic spinning core-shell fiber layer, sequentially repeating the steps (1), (2) and (3) for multiple times to obtain the mesoporous zeolite multilayer hemostatic gauze.
