nanofillers in polymers

As reported by the national nanotechnology initiative strategic plan in 2004, nanotechnology is “the understanding and control of matter at dimensions of roughly 1-100 nanometers” and it has become one of the most popular fields of development and research in many technical disciplines in the last 20 years. polymeric nanocomposites represent a new class of composite materials that generally exhibit better properties than traditional microcomposites in terms of mechanical properties, thermal and dimensional stability, gas permeability, fire and chemical resistance, optical and electrical properties, etc., and with lower loading levels. in this paper, the principal nanoparticles and their effects on the properties of polymeric matrix nanocomposites will be reviewed.
