Dark Blue

Poly(3,4-ethylenedi-oxythiophene) (PEDOT) derivatives conducting polymers are known for their great electrochromic (EC) properties offering a reversible blue switch under an applied voltage. Characterizations of symmetrical EC devices, built on combinations of PEDOT thin films, deposited with a bar coater from commercial inks, and separated by a lithium-based ionic membrane, show highest performance for 800 nm thickness. Tuning of the color is further achieved by mixing the PEDOT film with oxides. Taking, in particular, the example of optically inactive iron oxide Fe2O3, a dark blue to reddish switch, of which intensity depends on the oxide content, is reported. Careful evaluation of the chromaticity parameters L*, a*, and b*, with oxidizing/reducing potentials, evidences a possible monitoring of the bluish tint.

AMF anodization lithography was performed on organic thin films with conducting polymers which is poly(3,4-ethylenedioxythiophene). The conductivity of PEDOT thin films was changed by different dopants and organic solvents. Two different dopants are poly(4-styrenesulfonate) and di(2-ethylhexyl)-sulfosuccinate. Also, DMF and IPA were used to prepare the PEDOT thin films doped with PSS and DEHS on silicon surface. The conductivities of these PEDOT variants were compared by obtaining their I–V curves between tip and thin films using AFM. Silicon oxide nanopatterns with higher aspect ratios can be obtained from the films with higher conductivity.
