Abstract :

In this study, a modified electroless silver plating process was used to prepare the monodisperse Ag-coated polystyrene core-shell type particles (Ag-PS). Silver nuclei produced on polystyrene particles with an electroless plating method served as nucleation sites for the growth of silver shell. A scanning electron microscope (SEM) was used to observe the particle size and morphology of Ag-PS particles. The results showed that a dense, stable and uniform silver shell grew on the surface of PS particles to form the Ag-PS composite particles with the diameter of 3 �¼m. The bulk conductivity of the Ag-PS composites could achieve 2427 S/cm with only 36% silver content. According to the results, the Ag-PS composite particles have great potential to be used as fillers in anisotropic conductive films.
