![عکس صفحه اول مقاله: Effect of the organic–inorganic template ICS-PPG on sol–gel deposited V2O5 electrochromic thin film Effect of the organic–inorganic template ICS-PPG on sol–gel deposited V2O5 electrochromic thin film](/preview/png/80859.png)
We produced V2O5 thin films with sol–gel technique, using in the synthesis as a template agent, the so-called ICS-PPG. We studied the electrochromic behaviour of thin films with electrochemical techniques as slow scan cyclic voltammetry and cyclic voltammetry (SSCV, CV), impedance spectroscopy (EIS) and potentiostatic intermittent titration (PITT). Moreover, we measured transmittance spectra, optical bandgap of the material and, with the help of transmission electron microscopy (TEM), we found out informations about films structure. The addition of ICS-PPG produces more transparent samples in comparison with samples prepared without template agent. The ion storage capacity is only slightly increased and, with ageing, some deposits appear on the surface limiting the electrochemical performances.
