Application of sensor arrays based on thin films of conducting polymers for chemical recognition of volatile organic solvents

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.

AbstractA new approach to general sensors for odors and volatile organic compounds (VOCs) using thin films of chemically responsive dyes as a colorimetric sensor array is described. This optoelectronic “nose,” by using an array of multiple dyes whose colors change based on the full range of intermolecular interactions, provides enormous discriminatory power among odorants in a simple device that can be easily digitally imaged. High sensitivities (ppb) have been demonstrated for the detection of biologically important analytes such as amines, carboxylic acids, and thiols. By the proper choice of dyes and substrate, the array can be made essentially nonresponsive to changes in humidity.

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.
