Materials scientists have always sought to optimize materials properties. Typically, however, increased performance of one property is achieved at the expense of another. This book from MRS brings together ceramists, physicists, engineers and chemists to offer an interdisciplinary investigation of the relationships among synthesis, structure and properties of hybrid systems. Applications exploiting the unique properties, novel processing or tailorability of hybrids are discussed. More specifically, application of hybrids to coatings, elastomers, porous materials, sensors and optoelectronics are featured. Topics include: organic/inorganic hybrids by chemical synthesis or intercalation; synthesis, characterization and processing of organic/inorganic hybrid materials; organic/inorganic hybrid coatings; mechanical properties of selected organic/inorganic materials; organic/ inorganic hybrids - a route to controlled porosity materials; electrical and optical properties of organic/inorganic hybrid materials; and particulates and layered films.
