Polymer solution, electrospun nanofibrous membrane and preparation method therefor

Abstract

The present disclosure relates to a polymer solution, an electrospun nanofibrous membrane and a preparation method therefor, pertaining to the technical field of electrospinning. The polymer solution includes, in parts by weight, 5-20 parts by weight of an amorphous in vivo-degradable polymer, 0.5-3 parts by weight of a water-soluble polymer, 0.01-1.5 parts by weight of an antibacterial agent and a solvent. In the above, a weight-average molecular weight of the amorphous in vivo-degradable polymer is no less than 80 thousand. After the polymer solution forms the electrospun nanofibrous membrane, the electrospun nanofibrous membrane can make the antimicrobial agent well released and effectively suppress bacterial growth, thereby optimizing antibacterial efficacy of the electrospun nanofibrous membrane.
