POLYMER FIBER, PRODUCTION METHOD FOR SAME, AND PRODUCTION DEVICE

摘要

A polymer electrolyte fiber having a high molecular weight is produced with ease by an electrospinning method. In an electrospinning method which comprises applying a voltage to a solution of a polymer electrolyte to allow a jet of the solution to spurt, forming a polymer fiber, the voltage applied to the solution of the polymer electrolyte is a voltage having the opposite polarity to the charge of molecular chains of the polymer electrolyte in the solution, and the voltage is applied to increase the viscosity of the solution to be higher than that of the solution before applying the voltage, allowing the solution to spurt.
