Abstract:Composites with poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonic acid), PEDOT-PSS, as the matrix containing ZSM-5 zeolites of various Si/Al ratios in the range of 23-280 at 20% (v/v) were fabricated to investigate the effect of Si/Al ratios on electrical conductivity sensitivity responses towards carbon monoxide (CO). The electrical conductivity responses of PEDOT-PSS/ZSM-5 composites were altered due to the available adsorption sites for CO molecules. The electrical conductivity sensitivity to CO increases with decreasing Si/Al ratios. The composites produce irreversible responses when replacing CO with nitrogen. The addition of ZSM-5 zeolites to the pristine PEDOT-PSS improves the electrical conductivity sensitivity of the composites by enhancing the interaction between PEDOT-PSS and CO gas. The composite of ZSM-5 zeolites with a Si/Al ratio equal to 23 gives the highest electrical conductivity sensitivity toward CO.

Nanostructured hybrid thin films of the system tungsten oxide-poly͑3,4-ethylenedioxythiophene͒:poly͑styrenesulfonate͒ ͑WO 3 -PEDOT:PSS͒ were synthesized by first forming a tungsten-oxide layer by surfactant-assisted electrochemical method, followed by deposition of a PEDOT:PSS layer. The hybrid-film formation is primarily based on coulombic interactions between the surface hydroxyl groups of tungsten oxide and the positively charged centers on the polymer backbone; this has been confirmed by electron microscopy and X-ray diffraction. High-resolution transmission electron microscopy reveals that the tungsten-oxide host with a monoclinic unit cell resides along with the amorphous domains of PEDOT:PSS. The hybrid film, being a dual electrochrome, exhibits a much larger coloring efficiency ͑227 cm 2 C −1 at 600 nm͒, a higher redox activity ͑larger currents for ion ingress and egress are obtained within the same potential range͒, and, most importantly, a superior electrochemical cycling stability when compared to the neat polymer film. While the pristine polymer film lifts off irrevocably from the substrate upon 3000 cycles of coloring and bleaching, the hybrid film sustains about 5000 cycles, albeit with some changes in the nanoparticulate morphology, elemental composition, and development of some new artifacts on the film surface. The integration of organic and inorganic materials has aroused much interest in the scientific community for the use of hybrid organic-inorganic materials for catalysis, chiral synthesis, and enhancing electronic conductivity and electro-optical properties.1,2 To this end, this report describes a bilayer deposition of two different materials, an n-type semiconductor oxide, tungsten oxide ͑WO 3 ͒, and a p-type semiconductor, polymer ͑PEDOT:PSS͒, to yield a hybrid film and how its structure and composition influences the electrochemical and optical response and chemical stability of the film generated thereof. Since the discovery of electrochromism in WO 3 by Deb, 3 this oxide has been extensively investigated and has drawn considerable attention because of its application in electrochromic cells like smart windows, high-contrast displays, antiglare rearview mirrors, and so forth.4-6 PEDOT:PSS is one of the most widely studied electroactive polymers to date because of its excellent film forming ability, high conductivity, and high contrast ratio. [7][8][9] We found that the polymer forms a well-adherent uniform layer when deposited onto the WO 3 film, which indicates a strong affinity between the inorganic and organic species. The hybrid film offers the potential of realizing practical improvements of charge-transfer quanta through the bilayer/electrolyte interface and its reversibility as well. Furthermore, in the ever-growing field of solid-state electrochemical devices, the limited understanding of charge-transfer phenomena at the electrode-electrolyte interface is often a factor restricting operational lifetimes.In an approach to address these issues, in the past, PEDOT has been functio...
