Criterial parametrs for estimation of polymer solutions for electrospinning of fibers

Abstract

The possibility of estimating the high-elasticity state of solutions of polymers and oligomers by criterial parameters and dependencies was studied. It was found that the high elasticity of polymer solutions facilitates fiber formation in electroforming. The criteria used are dimensionless values of reduced viscosity and of reduced concentration, as well as the number of nodes in the physical entanglement of the macromolecules .
