توضیحات کتاب :
This chapter deals with composites comprised of polymers and inorganic nanoparticles of rather uniform shape. Such composites are attributed to the class of nanocomposites because of the small size of the embedded particles, while the polymer phase is continuous. The attribution of particles to the class of nanoparticles is somewhat arbitrary; often particles of dimensions up to 50–100 nm are assigned to this notion, and expressions such as nanosized particles, colloids, or, occasionally, ultrafine particles are also used to designate particles as nanoparticles. The small size of the incorporated particles can induce materials properties which differ from those of related composites containing larger particles, for example, as a result of an extremely large interface area, which can readily amount to 107–109 m2 in a cube meter of nanocomposite, or a markedly reduced scattering of visible light. The latter is important if transparent or translucent materials are required for optical applications. This intensity loss of transmitted light by scattering can be estimated with the equation
