POLYMER FIBER, PRODUCTION METHOD FOR SAME, AND PRODUCTION DEVICE

WIPO Patent Application WO/2011/142355

A1

Disclosed is a method for the simple production of a polymer electrolyte fiber with a high molecular weight, by an elecrospinning method.　Specifically disclosed is an electrospinning method wherein a voltage is applied to a polymer electrolyte solution and a jet of the solution is sprayed to form a polymer fiber. The voltage applied to the polymer electrolyte solution has the reverse polarity to the electric charge of the molecular chain in the polymer electrolyte solution and the application of the voltage increases viscosity to more than before the voltage was applied, to spray the solution.
