This is an excerpt from the content

In the last decades, polymer matrix nanocomposites (PMN) have been studied extensively to exploit the properties of nanofillers for transforming the nature of practical household materials, in particular for mechanical properties [1]. Despite the early successes [2], the massive interest in nanocomposites started in 1990s, when Toyota proved that adding mica to nylon produced a fivefold increase in the yield and tensile strength of the matrix material [3, 4]. Subsequent developments further contributed to the surging interest in polymer–nanoparticle composites. In particular, the growing availability of nanoparticles of monodispersed size and shape, such as fullerenes, carbon nanotubes, inorganic nanoparticles, dendrimers, and bionanoparticles, and the refining of instrumentation to probe nano-objects, such as scanning force, laser scanning fluorescence, and electron microscopes, have spurred research aimed at probing the influence of particle size and shape on the properties of PMN al
