Preparation and Conductivity of Organic-Tungstovanadophosphoric Acid Hybrid Materials

Abstract: Highly conducting hybrid materials were prepared from 90 wt% tungstovanadophosphoric heteropoly acids with Dawson structure (H 7 P 2 W 17 VO 62 or H 9 P 2 W 15 V 3 O 62 , abbreviated as P 2 W 17 V or P 2 W 15 V 3 ) and 10 wt% organic polymers (polyvinylpyrrolidone, PVP or polyethylene glycol, PEG). The result reveals that the conductivities of PVP/P 2 W 17 V, PEG/P 2 W 17 V, PVP/P 2 W 15 V 3 , and PEG/P 2 W 15 V 3 are 4.70 × 10 −3 , 1.02 × 10 −2 , 7.03 × 10 −3 , and 2.00 × 10 −2 S · cm −1 at 26 • C and 75% rel… Show more

“…To overcome these disadvantages, HPAs have been dispersed in organic polymer matrices or formed salts with some other cations such as organic ammonium to prepare various kinds of hybrid materials. 11,12 POM (especially with large cations) crystallize with fewer water molecular than pure acids and so they are less sensitive to the surrounding conditions. 13 The design and synthesis of these POM derivatives are of great interest for their potential applications in catalysis, medicine, electrochemistry and nanotechnology.…”
