This
study reports the preparation of hybrids of tungsten trioxide/polythiophene (WO3/PTh)
and tungsten trioxide/polyfuran (WO3/PFu)
using a rotating capacitively coupled radio frequency (rf) plasma process. The
prepared hybrid characteristics were measured using scanning electron microscopy-energy dispersive X-ray
spectroscopy (SEM-EDS) and X-ray diffraction analysis (XRD). WO3, WO3/PTh,
WO3/PFu thin films were deposited onto flexible substrates using electron
beam evaporation technique for high electrochromic performance purposes. The
effect of thiophene and furan moieties on the optical and electrochromic properties of the flexible hybrid-based ECDs was investigated using optical and electrochemical measurements. Especially, the WO3/PTh-based ECD shows marked
improvements of cathodic electrochromism over WO3-based ECD: the
optical contrast of 33% at 750 nm, the switching
times (bleaching time: 1.63 s, coloration time: 0.41 s), the coloration efficiency of 502 cm2/C.
