摘要：

Blends of the conducting polymer polypyrrole (PPy) and poly(vinyl alcohol) (PVA) were prepared electrochemically and characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, and scanning electron microscopy (SEM). The two polymers are intimately mixed at the molecular level as evidenced by (a) the loss of crystallinity of PVA in blends containing at least 20 % PPy and (b) new infrared absorption bands in the blends that are not found in the spectra of the pure homopolymers. The blends are produced as thin, conducting layers on the electrode as shown in SEM micrographs.
