ABSTRACT

Nanocomposite is a multiphase solid material where one of the phases has one, two or three dimensions of less than 100 nanometres(nm) or structures having nano-scale repeat distances between the different phases that make up the material. Nanocomposites are found in nature, for example in the structure of the abalone shell and bone. Taking material dimensions down to nanometre level creates phase interfaces which are very important for enhancement of materials properties. The ratio between surface area and volume of reinforced material used during nanocomposites preparation is directly involved in understanding of structure-property relationship. Nanocomposites are useful in medical, pharmaceutical industry, food packaging, electronics and energy industry. This review focus on the preparation, types and applications of nanocomposites. Nanocomposites are high performance materials which reveal rare properties. Nanocomposites have an estimated annual growth rate of 25% and fastest demand to be in engineering plastics and elastomers.
