Polypyrrole/conductive mica (PPy/CM) composites were prepared by coating polypyrrole (PPy) onto the
surfaces of the conductive mica (CM) via the in situ chemical oxidative polymerization method. The
encapsulating morphologies were revealed with the scanning electron microscopy (SEM) technique.
The PPy/CM composites were characterized with Fourier transform infrared (FTIR) spectroscopy, X-ray
diffraction (XRD), and thermogravimetric analysis (TGA). The composites possess high electrical con-
ductivity at room temperature, the weak temperature dependence of the conductivity. Based on the
cyclic voltammetry and the charge/discharge behavior of the PPy/CM composites, it was found that the
composites performed typical electrochemical supercapacitor behavior.
