This study aimed to investigate the effects of a corrosive environment on both the electrical and the water resistance properties of conductive paste based on gold/silver composites. The conductive paste was prepared by incorporating silver and gold powders, polyvinyl acetate, polyvinyl chloride as adhesive components, and methyl isobutyl ketone as a diluent. The gold/silver composite powder was prepared with different mass ratios of gold and silver. The paste was coated on a substrate and heated at 80℃ to form the conductive paste film. Characterizations of conductive paste were performed by using FT-IR spectroscopy, electrometry, cyclic voltammetry, and contact angle measurements. Thus, the conductive paste films were tested under two conditions: the absence and the presence of exposure to nitric acid vapor. The results showed that the resistance and the contact angle of the conductive paste were more stable after exposure to nitric acid vapor, particularly in samples of higher gold content. Furthermore, the electrochemical behavior of the conductive paste with gold content remains unchanged after exposure to nitric acid vapor. Results suggest that gold has properties in terms of stability, resistance to oxidation, and maintaining surface characteristics, making it a preferable component for applications requiring resistance to corrosive environments.

“…To counterbalance the pros and cons of both types of materials, we suggest mixtures of metal oxide and polymer as good candidates for electrochromic application. 26,27 The benefit of such an approach has been recently demonstrated through various examples. Among those hybrid composite materials, mixtures of poly(ethylene-3,4-dioxythiophene):poly(styrenesulfonicacid) (PEDOT:PSS) and WO 3 28 or with TiO 2 29 are characterized by good properties.…”

Niobium pentoxide, Nb2O5, exists in many polymorphs with diverse properties and morphologies that are dependent on the synthesis route. In this work, we design a new approach to fabricate and stabilize the metastable polymorph hexagonal nanoniobium pentoxide using soft chemistry and in particular the polyol synthesis. The electrochromic properties of homogeneous niobium pentoxide thin films deposited by Dip Coating, from as-synthesized hexagonal powder, are studied in lithium trifluoromethanesulfonimide (LiTFSI) in 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (EMITFSI) ionic liquid electrolyte versus Pt as counter electrode. The structure and morphology of the Nb2O5 thin films before and after cycling are characterized by ex-situ XRD and SEM while their optical and electrochemical properties are investigated by in-situ transmittance and cyclic voltammetry (CV), respectively. Thin films made from hexagonal Nb2O5 with spheres architecture exhibit good cycling stability, high transmittance modulations (ΔT≈33% at 550 nm), fast switching speeds (2 to 3 s for coloration and bleaching at 550 nm), and high coloration efficiency (CE≈26 cm 2 .C-1) with a good quality factor G(λ) = 10.4 cm 2 .C-1 .s-1. Finally, novel electrochromic devices based on hybrid thin films combining PEDOT:PSS and oxides are assembled showing enhanced coloration and simultaneous color change due to their double sided configuration.
