Preparation method of material for puncture-resistant artificial blood vessel and artificial blood vessel prepared thereby

A preparation method of a material for a puncture-resistant artificial blood vessel, including the following steps:

• S1:
• dissolving a polymer into a solvent to obtain a polymer solution with a concentration w/v of 10-70%, and stirring the polymer solution at a room temperature for 5-48 h;
• S2:
• placing the polymer solution obtained in S1 over a mandrel device and performing electrospinning to obtain a porous electrospun inner layer, drying the inner layer for 5-48 h to remove the residual solvent;
• and
• S3:
• with the inner layer obtained in S2 as a receiving surface, performing first electric spray, second electric spray, nth electric spray with the polymer solution to obtain a dense outer layer, thereby forming the material for the puncture-resistant artificial blood vessel;
• wherein a process of the first electric spray includes spraying, stopping, spraying, stopping, repeated cycles, a time of the stopping in the process of the first electric spray is 5-20 min;
• and
• a time of each of the first electric spray, the second electric spray and the nth electric spray is 5-50 min.
