ABSTRACT
Polymer nanocomposites are an important class of materials, which are an alternative to the conventionally filled polymers. These are materials in which nanosized inorganic fillers, typically 1-100 nm in at least one dimension, are individually dispersed in a polymer matrix. Because of the nanometer sizes of the filler, nanocomposites exhibit markedly improved properties as compared to the pure polymers or their conventional composites. These include increased modulus and strength, outstanding barrier properties, improved solvent and heat resistance, and decreased flammability (Lagashetty and Venkataraman, 2005).
