ELECTROLESS PLATING PROCESS OF CROSSLINKED MONODISPERSE POLYMER PARTICLES WITH A DIAMETER OF MICRON AND THE PLATED PARTICLES THEREFROM

摘要

The electroless plating method of a monodisperse cross-linked polymer particle with a micron size and the powder of its plating are arranged to improve electroplating evenness and reproducibility are electroplated by updating an electroplate liquid into method or by the controlling pH of initial plating time. One electroless plating method of the monodisperse cross-linked polymer particle with a micron size includes the step that a thin pulp is obtained by executing catalyst operation, uses stannic chloride and palladium chloride by using a cross-linked polymer particle; It is inserted into the step that thin pulp enters an electroplating bath, the controlling pH of thin pulp enters a metal salt solution and a reducing agent solution by dividing electroplate liquid and enters thin pulp by dropping method insertion electroplate liquid than the pH high in 1~3 degree of normal plating conditions; The step for executing the electroplating operations of the entire plating time for 1/100~1/5%, by keeping a kind of color of its thin pulp of the pH of a period of time to be changed dark point; The step for continuing through the electroplating reaction of dropping method insertion electroplate liquid, in control after the pH of the thin pulp of the pH of normal plating conditions.
