The paper describes the process of obtaining electrospun nanofibers from solutions of polyvinyl chloride in tetrahydrofuran and in a mixture of tetrahydrofuran and dimethylformamide. The regularity of size variation of polyvinyl chloride nanofibers depending on the selected technological parameters was analyzed. The optimal formulation for the preparation of the polymer solution was chosen on the basis of the obtained experimental data. That developed formulation ensures the stability of the electrospinning of nanofibers with desired morphological characteristics. The results of the experiment show that increasing of polyvinyl chloride concentration from 10 to 30 mass. % leads to increasing in the diameter of electrospinning nanofibers based on polyvinyl chloride from 291 nm to 395 nm. The tensile strength and tensile modulus for electrospun nanofiber films based on polyvinyl chloride are 2.21 MPa and 53.2 MPa, respectively.
