Abstract
First, the poly(3-methylthiophene) (PMeT) and the polyaniline
(PANI) of the conductive polymer electrochromic thin films had been deposited
on the indium tin oxide/glass (ITO/Glass) substrate by cyclic vltammetry (CV)
and applied to electrochromic display (ECD) were investigated with different
molarity electrolyte solutions to obtain optimal parameters in order to improve
homogeneous and reversible deposition. Second, the PMeT and PANI thin films
were investigated with different scan rates of deposition to obtain optimal
parameters in order to improve property and applied to ECD. The optical, electrical
and color properties of PMeT and PANI thin films were analyzed by using ultraviolet-visible
(UV-Vis) spectroscopy, electrochemical impedance spectroscopy (EIS), CV measurement
system, and micro spectroscopy. The ECD which with PMeT thin film fabricated
at 200 mV/s (sample PMeT200) has the highest transmittance variation (
$\triangle {\rm T}_{450~{\rm nm}}=15~\%$
and
$\triangle
{\rm T}_{650~{\rm nm}} = 40~\%$
) and the response time are
14 s
$({\rm T}_{450~{\rm
nm}})$
and 15 s
$({\rm
T}_{650~{\rm nm}})$
, respectively. The CIE 1931 chromaticity
coordinates of ECD which with PMeT thin film fabricated at 200 mV/s (sample
PMeT200) has the best shape of tracks. The PANI thin film fabricated at 200
mV/s (samplePANI200) has the highest transmittance variation
$(\triangle {\rm T}_{550~{\rm nm}} = 24~\%)$
.
The CIE 1931 chromaticity coordinates of PANI thin film fabricated at 200
mV/s (sample PANI200) has the best shape of tracks.
