Definitions

  • An object of the present invention is to provide a conductive polymer particle having a metal layer having excellent electrical conductivity and at the same time excellent corrosion resistance and bonding strength with the polymer particle.
  • the third layer may include 0.1 to 13.0% by weight of phosphorus together with nickel.
  • the first layer may further include palladium, and by including palladium, bonding between the surface of the polymer particle and silver oxide and bonding between the second layer may be further strengthened.
  • the amount of palladium contained may be much smaller than that contained in conventional conductive polymer particles without silver oxide.
  • the amount of palladium used in the manufacturing process of the conductive polymer particles is generally in the range of 100 to 1,000 ppm based on the conductive polymer particles, but the amount of palladium used in the conductive polymer particles according to the present invention exceeds 0 and is less than 50 ppm.
  • the metal silver or silver oxide formed in the first layer must have a certain amount or more to provide a satisfactory bonding force to the second layer, and if it is too large, process costs increase, which is undesirable. More preferably, it may be 10 to 500 ppm.
  • a hydrophilization step of hydrophilizing the surface of the polymer particle (b) a first layer formation step of coating silver oxide on the polymer particle whose surface is hydrophilic, (c) on the first layer
  • a conductive polymer manufacturing method comprising the step of forming a second layer of electrolessly plating copper and (d) the step of forming a third layer of electroless plating of nickel or silver on the second layer.
  • the hydrophilization treatment of the polymer particles can be carried out in the aqueous solution of strong alkali as described above, but by modifying the surface of the polymer particles through plasma treatment, it is also possible to hydrophilize the polymer particles dry.
  • Example 2 In the same manner as in Example 1, a hydrophilization treatment and a tin layer were formed. Thereafter, electroless plating was performed immediately without forming a silver oxide layer to sequentially form a second layer containing copper and a third layer containing nickel. Electroless plating of copper and nickel was performed in the same manner as in Example 1.
