Nanocomposite Dielectric Materials for Organic Flexible Electronics

This chapter summarizes the application of polymer nanocomposites functioning as dielectric materials for organic flexible electronics. In the nanocomposite dielectrics, polymers are serving as the matrix and inorganic fillers are used to increase the effective dielectric constant while functionalization of the nanoparticle fillers is carried out to improve the compatibility with polymers. We discuss the dielectric characterization of the composites, such as the dielectric permittivity and the leakage current. The electrical performance of the capacitors, transistors, and inverters under different applied strain on flexible substrates is also described. The nanocomposite dielectric layer should be an excellent insulator candidate for the future development on portable displays, conformable sensors, and other flexible electronics application. © 2014 Elsevier Ltd.
