Composite type porous crosslinking breast patch and preparation method thereof

The invention belongs to the technical field of tissue engineering, and in particular relates to a composite type porous crosslinking breast patch and a preparation method thereof. The composite type porous crosslinking breast patch adopts a double-layer structure; through combined use of the double-layer structure, excellent histocompatibility and degradability of the material are guaranteed, and complication such as prosthesis shift caused by the fact that the material is degraded too fast is avoided; and according to the preparation method of the composite type porous crosslinking breast patch, a crosslinking layer and a non-crosslinking layer are subjected to special adhesion and freeze drying and then are punched to prepare the composite type porous crosslinking breast patch, so the method is easy to industrialize and has good market application value.
