PAN Fabrication Methods of Spinning Solution for Conductive Polyacrylonitrile PAN Fibers

摘要

PURPOSE: A manufacturing method of a spinning solution of conductive polyacrylonitrile fiber is provided which is characterized by being possible to use an existing process, dissolving sulfonated polyaniline(SPAN) and polyacrylonitrile(PAN) simultaneously to produce the spinning solution and being possible to produce the conductive polyacrylonitrile fiber having high value added. CONSTITUTION: On producing the conductive polyacrylonitrile fiber, sulfonated polyaniline and polyacrylonitrile are blended in a composing ratio of 0.01:99.99 - 99.99:0.01. On producing the spinning solution, a DMSO-base solvent is used. The solvent is obtained by adding base(NH4OH, NaOH, NH3gas and so on) to dimethylsulfoxide(DMSO). A coagulating bath is filled with an acidic aqueous solution or an acidic organic solvent.
