| dc.description.abstractEn | Electrochromism is known as a modulation of the optical properties under an applied voltage. Among conductive polymers, poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) switching from a neutral to reduced blue state, existing as commercial ink, allows to address displays applications. Aiming at enlarging the color panel, we recently developed an approach based on the addition of oxides leading to PEDOT-PSS + Oxides composites. Particularly, in this work, the influence of the incorporation of Fe2O3 on the electrochromic properties of the PEDOT:PSS based films deposited by bar coater are studied. The electrochemical and optical characterizations of the hybrid composite films PEDOT:PSS/Fe2O3 by chronoamperometric (CA) coupled with in situ UV–visible spectroscopy, indicate that the hybrid composite film with 420 nm thickness shows a reversible switch from blue to red associated with a coloration efficiency of (CE = 37 cm2 C−1) at 650 nm and transmittance modulation (ΔT = 22%) in lithium based electrolytes with switching speeds in the order of the sec. All these results suggest that the hybrid composite films, combining the benefit of mixing inorganic and organic materials, are promising materials for electrochromic devices. | |
