Preparation and characterization of monodispersed PS/Ag composite microspheres through modified electroless plating

► PS/Ag composite microspheres have great potential to be used as fillers of ACFs. ► Uniform colloidal Pt of approximate 10 nm is used as catalytic centers. ► Increasing concentration of silver precursors enables growth of silver shell. ► PVP used as stabilizer to protect PS/Ag microspheres from aggregation. ► Monodispersed PS/Ag composite microspheres have good conductivity.
