The preparing method of conductive long fiber coated with silver nanoparticles and the conductive long fiber coated with silver nanoparticles thereby

摘要

It is an object of the present invention to provide a method for producing a silver-plated conductive filament and a silver-plated conductive filament prepared thereby. For this purpose, the present invention relates to polyamideimides (poly (amide-co-imide)) and poly (trimellitic anhydride chloride-co-4,4'- methylenedianiline) is dissolved in a solvent at a weight ratio of 4.5: 5.5 to 5.5: 4.5, followed by mixing (Step 1); Preparing a long fiber by electrospinning the mixed solution of step 1 (step 2); And forming silver nanoparticles on the surface of the long fiber of step 2 (step 3). The present invention relates to a method for manufacturing silver-plated conductive filaments by producing long fibers using polyamideimide and polytrimellitic anhydride chloride-4,4'-methylenedianiline as raw materials, , There is an effect that the silver nanoparticles can be homogeneously plated by activating the surface of the long fiber with a polyethylene glycol solution. The long fibers prepared according to the present invention can exhibit excellent conductivity as silver nanoparticles are plated on the surface of the fibers, and thus can be used as an electrode material.
