Synthesis and Structure of Polypyrrole Derivatives／V2O5 Nanocomposites

Poly ( N, N, N-trimethyl ( 2-pyrrol-l-yl ) ethyl ammonium iodide )/V2O5 ( PTPAI/V2O5) nanocomposites were synthesized by sol-gel method. This method involved formation of vanadium pentoxide xerogel in the prcscnce of polypyrrole derivatives solution. X-ray diffraction(XRD) indicated that the polypyrrole derivative particles encapsulated in the fibrous V2O5 network and the layered distance significantly increased from 1. 077 39 to 1. 354 56 nm. The interaction between polypyrrole and V2O5 in the ‘nanocomposites‘ was characterized by IR spectroscopy. The Scanning Electron Microscope(SEM) micrographs reveal the structural contrasts between the hybrid materials and the pristine vanadium oxide xerogel.
