Preparation of new inorganic–organic complexes by using FexTi1–2xNb1+xO5 – (x = 0–0.5) nanosheets

Novel inorganic–organic complex nanocomposites have been prepared by using exfoliated FexTi1–2x Nb1+xO5 – nanosheets and poly (N-octadecyl-2-ethynyl pyridinium bromide) (PNOEtPyBr) by the method of exfoliation–reflocculation. The X-ray diffraction data of the nanocomposites indicate the formation of FexTi1–2x Nb1+xO5/PNOEtPyBr nanostructure with the length of basal spacing of 4.6 nm along the stacking direction of FexTi1–2xNb1+xO5 – nanosheet layers. The a. c. electrical conductivity of nanocomposites decreased with the value of x. This trend was correlated with the hydration behavior of the interlayer for HFexTi1–2xNb1+xO5 nH2O (x = 0–0.5) which were starting compounds of nanosheets.
