are two phase systems, which
consist of a polymeric matrix and nano-fillers dispersed in the
matrix. The most frequently used inorganic fillers in polymer nanocomposites
belong to a family of 2:1 phyllosilicates, which have
a sheet silicate structure. Montmorillonite, hectorite and vermiculite
are amongst the most commonly used fillers in polymer-clay
nanocomposites
