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
