Abstract
A method for preparing an elastic conductive fiber, which includes: immersing an elastic polyurethane fiber in an alkaline solution containing a base selected from the group consisting of triethylamine and sodium hydroxide, so as to obtain an alkaline-treated elastic polyurethane fiber; immersing the alkaline-treated elastic polyurethane fiber in a first treating composition containing a metal trifluoroacetate and an alcohol solvent, so as to obtain a processed elastic polyurethane fiber containing the metal trifluoroacetate; and immersing the processed elastic polyurethane fiber in a second treating composition containing water and a reducing agent, so that a metal particle is formed on a surface of the processed elastic polyurethane fiber by reducing metallic ions in the metal trifluoroacetate.
