Abstract

The hydrothermal treatment of vanadium pentoxide xerogel previously intercalated with long-chain primary amines leads to micro and nano-tubular products whose walls are conformed by amine bilayers sandwiched between V 2O5 lamellae. The microcrystalline powder product may be partially ordered at a macroscopic scale by pressure. Effects of the pressure are observed in the morphology, the intensity of the reflections in the X-ray diffractograms as well as in the electrical conductivity. The anisotropy degree estimated as the ratio of the electrical conductivities perpendicular and parallel to the direction of the applied pressure is about 102 at room temperature.
