Abstract

Intercalation of basic surfactant molecules into the layered perovskites H[Ca₂Na_n−3Nb_nO_3n+1], n = 3–5, can be used to cause spontaneous exfoliation of the structure into thin sheets that form stable dispersions in a polar solvent. The extent of exfoliation has been determined by examining Rutherford scattered intensities into a high-angle annular dark-field detector in a scanning transmission electron microscope. It is shown that for n ≤ 5, the layered perovskites can be exfoliated to form single layers. Exfoliation is easiest for the n = 3 and 4 materials.
