【 摘 要 】

A new route for the in-situ formation of silver-polypyrrole (Ag-PPy) on the layer of SiO2@poly(sodium styrene sulphonate) (SiO2@PSS/AgPPy) composite particles, using SiO2@poly(sodium styrene sulphonate) (SiO2@PSS) particles as a template is presented. The template SiO2@PSS consisting of a SiO2 core and PSS on the surface was prepared by the ‘grafting from’ approach. SiO2@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 SiO2@PSS/Ag-PPy composites consisting of a spherical structure with a diameter of about 80 nm were successfully fabricated.
