Abstract

A method for electrostatic spinning of thermoplastic polymers for obtaining nano and microfibers, is introduced. The method if characterized by the following steps: solving the thermoplastic polymer in a corresponding solvent; adding a thermoplastic elastomer (TPE) to this solution, and introducing the solution into an electric field and spinning under the effect of the electric field to nano and microfibers.
