Preparation, characterization and properties of polypyrrole vanadotungstogermanic triheteropoly acid hybrid material

Polypyrrole (PPy) hybrid material doped vanadotungstogermanic triheteropoly acid was prepared for the first time. Their SEM, IR and XRD patterns confirm the existence of Keggin anions and form the space reticular structure. The material exhibits excellent proton conduction, its proton conductivity is 1.24×10−2 S cm−1 at room temperature (18 °C).
