23 Jul Composite scaffold material and preparation method and application thereof
Abstract
The invention relates to the technical field of medicine, in particular to a composite scaffold material and a preparation method and application thereof. The provided composite scaffold material includes a charged fiber skeleton material, and the fiber skeleton material is coated with alternately superimposed positive charge biocompatibility materials and negative charge biocompatibility materials through electrostatic attraction. As the fiber skeleton material is coated with the alternately superimposed positive charge biocompatibility materials and negative charge biocompatibility materialsthrough electrostatic attraction, the provided composite scaffold material overcomes the defects of an existing scaffold material, such as poor hydrophilicity, poor biocompatibility, poor histocyte adhesion ability and weak biological induction activity, has better applicability when used in tissue adhesion, sealing, leaking stoppage, hemostasis, isolation, repair and adhesion prevention and thelike, and can be used for preparation of carriers (such as sustained release carriers) of drugs, tissue engineering scaffold materials and the like, and thus the composite scaffold material can be widely used.
