Title:
PREPARATION METHOD FOR BIOACTIVE SUBSTANCE COATED POLYESTER MESH LAYER SCAFFOLD
Document Type and Number:
WIPO Patent Application WO/2022/241852
Kind Code:
A1
Abstract:
A preparation method for a bioactive substance coated polyester mesh layer scaffold, which comprises the following steps: forming a mesh layer from a polyester material by means of spun bonding and reinforcement; washing and drying the mesh layer; utilizing a strong alkaline solution to perform carboxylation treatment on the washed and dried mesh layer; performing activation and crosslinking on the mesh layer; performing repeated coupling on the mesh layer to form a bioactive substance coating on the mesh layer; performing blocking on the coated mesh layer, and obtaining a bioactive substance coated polyester mesh layer scaffold.
