Abstract : Nano has now become a theme in almost all the established discipline. The confluence of innovative methodologies, sophisticated characterisation techniques, and potential technological utility has resulted in intense research activity in the field of polymer nano composites. Polymer composites made out of nano materials display unique properties in terms of improved tensile strength, flexibility, and flexural endurance. The paper discusses the development of polymerclay nano composites, both from the conceptual point of view as well as practical methods for the synthesis of nano composites. These are monomer intercalation, monomer modification, common solvent, and melt-intercalation methods. Various models have been discussed that describe improvements in mechanical and barriers properties due to the incorporation of nano materials. Ongoing R&D work in the two DRDO laboratories on the development of nano composites has been briefly mentioned. The emerging use of polymer-nano composites has also been described.
