Reinforced electrospun fibrous membrane and preparation method thereof

Abstract

The present disclosure discloses reinforced electrospun fibrous membranes and preparation methods therefor. The reinforced electrospun fibrous membranes can include an electrospun fibrous membrane body and a plurality of reinforcing thread sets fixed to the electrospun fibrous membrane body through holes thereon, wherein any two of the plurality of reinforcing thread sets are parallel to each other; each of the reinforcing thread sets comprises a starting end and a terminal end, both being connected to an edge of the electrospun fibrous membrane body; each of the reinforcing thread sets comprises at least one reinforcing fibrous thread consisting of a main thread and an auxiliary thread respectively arranged at a front side and a bottom side of the electrospun fibrous membrane body and configured to interlace each other at the through hole. By providing reinforcing thread sets on the electrospun fibrous membrane body to impart the electrospun fibrous membrane with a greater mechanical property, the mechanical strength required for the movement of the tissue is ensured, and the electrospun fibrous membrane is easy to be folded or rolled into other shapes. The electrospun fibrous membrane body may be made of degradable materials, which are gradually degraded and absorbed in the process of inducing new tissue formation, thereby providing space for the formation of new tissues.
