Template characterizations, mainly op tical investigations of ordered porous alumina, and physical principles underlying wetting phe nomena are investigated first. Micro and nano tubular structures, consisting of either inorganicferroelectric oxides such as lead zirconate titanate (PZT) or barium titanate (BTO), or organic copolymers such as P(VDF co TrFE), are obtained by wetting of the porous tem plates. Their physical properties, particularly crystallinity and ferroelectric switchings, are ex plored by X ray diffraction and Scanning force microscopy, respectively.
