Abstract :
Polypyrrole-coated V2O5 nanotubes hybrid materials have been synthesized through an in situ polymerization of pyrrole monomers in the presence of prepared V2O5 nanotubes. The hybrids were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Experimental data showed that polypyrrole was uniformly coated on the surface of the V2O5 nanotubes, and the polypyrrole coating is 30 nm thick. Gas sensing tests showed that the hybrids possessed very high sensitivity to ethanol gas at room temperature, implying its potential application for gas sensors.
