摘要：
Novel vanadium dioxide nanorods were fabricated from V2O5 in the presence of a reducing agent, the poly(diallyldimethylammonium chloride) (PDDA) via a hydrothermal method at 180 degrees C for 48 h. The samples produced were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared spectroscopy (FTIR), nitrogen adsorption (BET) and thermogravimetry (TG/DTG). The nanorods obtained are approximately 50 nm wide and from 300 to 500 nm long and presents high surface area (42 m(2) g(-1)). The nanocrystalline B phase VO2 is not produced by hydrothermal treatment in the absence of the PDDA polyelectrolyte. (C) 2010 Elsevier Ltd. All rights reserved.
