Abstract: To fabricate ferroelectric ultrathin polymer films with large dielectric constants for potential all‐organic electronic devices, ferroelectric polymer nanotubes and a composite of the nanotubes with a dispersed organic semiconductor have been fabricated by template‐assisted methods. The ferroelectricity drops markedly in spin‐coated ultrathin films less than 100 nm thick, whereas P(VDF‐TrFE) nanotubes with a wall thickness of a few ten nm sustain ferroelectricity. The composite nanotubes exhibit a giant dielec… Show more

“…Polymer melts can be infiltrated into AAO pores, and structure formation under the hard confinement imposed by the rigid AAO pore walls can be controlled by application of appropriate temperature profiles . Therefore, self‐ordered AAO has been explored as inorganic model component to study crystallization, dynamics, and interphases of polymers in rigid cylindrical confinement . Thus, the results obtained here may also shed light on the behavior of THV at solid surfaces and in hybrid materials.…”

“…Because of the ongoing demand for miniaturization and lightweight of electrical and electronic devices, it poses an urgent challenge on current dielectric materials in terms of energy density as well as temperature stability. It seems that the emerging ferroelectric polymers (e.g., poly (vinylidene fluoride) [PVDF] and its copolymers), which possess spontaneous polarization and large permittivity (ε r ≈10–50), provide a promising solution to meet the ever‐increasing requirement for high energy density, especially when incorporating with further material modification through nanocomposites, blending, laminated structure, cross‐linking, and so on.…”

“…Polymer nanowires were also synthesized using 30 nm pore size AAO template [25,26]. Similar techniques based on wetting template methods were used to synthesize arrays of polymer nanotubes made from conductive polymers [27][28][29], ferroelectric polymers [30], elastic polymers [31], semiconducting polymers [32], nonpolar polymers [33], poly(vinyl pyrrolidone) [34], and magnetic molecularly imprinted polymers [35]. Insulating polymers such as polyamide 66 were used to make nanotubes to coat Pt nanowires, thus forming nanocables [36][37][38]…”
