Organic/silica nanocomposites were prepared by casting the blend solution of organic polymer, poly(2‐vinly pyridine‐co‐methyl methacrylate‐co‐2‐hydroxyethyl methacrylate) or poly(2‐vinly pyridine‐co‐2‐hydroxyethyl methacrylate), and perhydropolysilazane and/or cobalt acetate. Electrical properties of the organic polymer and the composites were measured. Hybridization with perhydropolysilazane and/or cobalt acetate drastically reduced leakage current of the polymer film at 1 MV/cm from 1 × 10 −7 to 1 × 10 −9 A/cm 2 without changing refractive index, dielectric constant and filed breakdown. Nanostructures and thermal stability of the composites were investigated. Copyright © 2005 John Wiley & Sons, Ltd.
