23 Jul Highly-tough hole-adjustable gel artificial blood vessel and making method thereof
Abstract
The invention relates to a highly-tough hole-adjustable gel artificial blood vessel and a making method thereof. The gel artificial blood vessel contains, by mass, 9-15% of an olefin monomer M1, 1-3% of a biological polymer M2, 0-0.02% of a chemical crosslinking agent M3 and 4-10% of an ionic crosslinking agent M4. The making method comprises the following steps: making a gel artificial blood vessel base by using the M1 and M2 as functional monomers and the M3 as a chemical crosslinking agent in an aqueous solution, and reinforcing by utilizing the M4 as an ionic crosslinking agent to make the highly-tough hole-adjustable gel artificial blood vessel. The gel artificial blood vessel made through the method has the advantages of high strength, toughness and resilience, difficult damage under the action of external forces comprising the pulling, bending, twisting and the like, rapid original shape recovery, multi-crosslinked network structure, and adjustment of the hole dimension through a crosslinking degree. The gel artificial blood vessel is suitable for the biological field, the medical field, the tissue engineering field, the adsorption field and the like.
