Synthesis and characterization of an VOPO_4-polyaniline lamellar hybrid compound

摘要

Taking into account the oxidant properties of vanadium (V) compounds, the lamellar matrix VOPO_4 ·2H_2O is used as an oxidant agent towards aniline, giving as product an VOPO_4-polyaniline intercalation compound of formula VOPO_4·(C_6H_4N)_(1.1) which exhibits an interlayer distance of 1.6 nm. The SEM micrographs obtained for the VOPO_4-Pani hybrid matrix shows that the microstructure of VOPO_4·2H_2O is changed after reaction, with a total exfoliation of the oxovanadium matrix, as well as a decrease of the crystallite grain sizes.
