Abstract

Vanadium pentoxide (V2O5) and multiwalled carbon nanotubes added V2O5 composite (MWCNT/V2O5) films were prepared by hydrothermal technique. The influence of various levels of MWCNT on the electrochromic properties of MWCNT/V2O5 films was investigated. X-ray diffraction analysis revealed that the films are polycrystalline in nature and belong to orthorhombic crystal system of V2O5. Raman and FTIR spectral analyses confirmed the formation of V2O5 phase and the influence of MWCNT on the vibrational frequencies of V2O5 films. V2O5 film added with 1 wt.% MWCNT showed enhanced transmittance and the bandgap of V2O5 increases with further increase in the addition of MWCNT in V2O5 films. The electrochromic studies revealed electrochromic reversibility of 82% (1 wt.% MWCNT added film) and 82.5% (5 wt.% MWCNT added film) whereas after 100 cycles the films added with 1 wt.% and 5 wt.% of MWCNT acquired excellent electrochromic reversibility of 92% and 88%, respectively. Further the switching kinetics of the film added with 1 wt.% MWCNT is 1.8 s for coloration and 2.4 s for bleaching processes.
