摘要
A new nanocomposite of vanadium pentoxide (V_2O_5) and polyaniline (PANI)were synthesized by in situ oxidative polymerization/intercalation on V_2O_5 powder at roomtemperature. The reaction was facile and topotactic, forming polyaniline as the emeraldine salt. Itwas indicated that V_2O_5 itself can catalyze the oxidative polymerization of aniline and thatlayered structure could make aniline intercalate into the V_2O_5 framework. It makes the in situpolymerization feasible to occur in the layer of V_2O_5 structure. XRD results showed PANI/V_2O_5nanocomposite possessed lamellar mesostructure, which was determined by an X-ray diffraction peak at6.5° and SEM photograph. And FT-IR spectrum suggested that there was interaction between PANI andV_2O_5. The hybrid had better thermal stability in N_2 and air ambience.
