Synthesis and structural properties of polypyrroleano-Y_2O_3 conducting composite

摘要

In this work, polypyrroleano-Y_2O_3 conducting composite was synthesized by chemical oxidative polymerization. The composite was characterized using transmission electron microscopy, X-ray diffraction, Fourier-transform infrared spectra, UV-vis absorption spectra, X-ray photoelectron spectroscopy and electrical conductivity measurements. The results indicate that Y_2O_3 nanoparticles are almost enwrapped by polypyrrole. The addition of Y_2O_3 nanoparticles results in changes in the surface structure and conductivity of the composite. Thermogravimetric analysis shows that composite has better thermal stability than that of pure polypyrrole.
