Dielectric Constant, Loss and Breakdown for Ultem containing BaTiO3 Nanoparticles

Lomax E.A., Lomax J.F., Lomax E.A., Lomax J.F., Lu S.C., Calame J.P., Fontanella J.J., Edmondson C.A., Wintersgill M.C., U.S. Naval Academy, US

The need for improved energy storage devices prompts interest in developing new dielectric materials for high energy capacitors. This work reports data on the properties of cast films of BaTiO3 nanoparticles (high dielectric) in the [...]

Permittivity of BaTiO3 polymer composite with differing particle size distribution

Schumacher B., Geßwein H., Hanemann T., Haußelt J., Forschungszentrum Karlsruhe GmbH, DE

In previous works the authors presented the possibility to raise the permittivity of polyester-reactive-resin composite materials by using thermal treatment steps to optimize the crystal structure of a nano-powder before incorporating it into the composite. [...]

Research on Preparation of Nano-Barium Titanate and Dielectric Property of Barium Titanate Ceramic Capacitor

Feng X., Liu X., Cui Y., Institute of Electronic Engineering, CN

In this paper ,a mild alcohol-thermal synthesis of nano-BaTiO3 from H2TiO3 and Ba(OH)2 at an Atmospheric Press was systematically studied and the optimized preparation conditions were obtained. When the reaction was carried out at a [...]

Ferroelectric Properties of FIB-prepared Single Crystal BaTiO3 Nanocapacitors

Schilling A., Saad MM., Baxter P., Adams TB., Bowman RM., Gregg JM., Morisson FD., Scott JF., Queen's University, Belfast & Nanotec NI, UK

Measurements on free standing single crystal barium strontium titanate capacitors made using focused ion beam micromachining with thicknesses down to 75 nm, show a dielectric response typical of large single crystals, rather than conventional thin [...]
