Abstract: | A novel n-pentylamine-intercalated layered perovskite-type oxide, C5H11NH3-Sr2Nb3O10, was prepared and characterized by using XRD, FT-IR, Raman spec-trascopy, and elemental analysis. It was shown that the intercalated n-pentylamine adopted a bilayer formation with some overlap and tilt, and the lattice of the perovskite layer was distorted due to the intercalation of n-pentylamine. The as-prepared sample gave clear electric hysteresis loop and did not show fatigue after 1011 switching circles, and therefore, could be considered as a new kind of fatigue-free ferroelectric materials. |
