A new route for the in‐situ formation of silver‐polypyrrole (Ag‐PPy) on the layer of SiO 2 @poly(sodium styrene sulphonate) (SiO 2 @PSS/Ag‐PPy) composite particles, using SiO 2 @poly(sodium styrene sulphonate) (SiO 2 @PSS) particles as a template is presented. The template SiO 2 @PSS consisting of a SiO 2 core and PSS on the surface was prepared by the ‘grafting from’ approach. SiO 2 @PSS/Ag‐PPy was characterised by transmission electron microscopy, X‐ray powder diffraction, energy‐dispersive X‐ray spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopic analysis, thermo‐gravimetric analysis and differential thermal analysis. The results showed that the SiO 2 @PSS/Ag‐PPy composites consisting of a spherical structure with a diameter of about 80 nm were successfully fabricated.
