ELECTROCHROMIC NANOCOMPOSITE FILM BASED ON MONOLACUNARY DAWSON-TYPE POLYOXOMETALATE AND TIO2 NANOWIRES
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
Electrochromic (EC) nanocomposite films consisting of monolacunary Dawson-type polyoxometalates (POMs) K10P2W17O61 (P2W17) and TiO2 nanowires (TiO2 NW) were fabricated by combining hydrothermal and sol-gel spin coating assembly methods. The surface morphology and the homogeneity of the nanocomposite films were characterized by Scanning Electron Microscope (SEM). The electrochemical and electrochromic (EC) performances were examined by UV-vis spectra and chronoamperometric (CA) measurements. Compared with individual P2W17 and TiO2 NW structures, the nanocomposite film exhibits improved EC properties with suitable optical contrast (15.69% at 650 nm) and fast switching times (2.98 s and 0.82 s)
