Transparent and flexible polymerized graphite oxide thin film with frequency-dependent dielectric constant

Abstract

Here we report on the preparation of transparent and flexible polymerized graphite oxide, which is composed of carbons with s p3 -hybridized orbitals and a nonplanar ring structure, and which demonstrates dispersion in its dielectric constant at room temperature. This frequency dependence renders the material suitable for creating miniaturized, flexible, and transparent variable capacitors, allowing for smaller and simpler integrated electronic devices. We discuss this polarizability in terms of space charge effects. © 2009 American Institute of Physics.
