Novel inorganic–organic complex nanocomposites have been prepared by using exfoliated FexTi1−2xNb1+xO 5 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 FexTi1−2xNb1+xO5/PNOEtPyBr nanostructure with the length of basal spacing of 4.6 nm along the stacking direction of FexTi1−2xNb1+xO 5 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.
