The word 'composite' refers to a macroscopic combination of two or more different materials that result in a new material having much improved and new characteristics. Nanocomposites are the composites consisting of multiphase materials in which at least one of the phases lies in the nanometric size domain (Inm-I00 nm). The Hybrid Nanocomposites (HNCs) are the multi-component compounds in which at least one of the constituents (organic or inorganic) has dimensions in the nanometre range with some interaction between them. The diverse and advanced technological applications of organic and inorganic materials are restricted owing to poor conductivity, lesser stability and solubility of organic materials and complicated processability and high-temperature operation of inorganic materials. However, in HNCs, the guest-host chemistry may help to overcome their particular limitations due to synergetic effects that lead to emerging research in the area of advanced functional materials. In HNCs, the interactions at the molecular and supra-molecular level result in modulation of mechanical, optical, electrical, catalytic and electrochemical properties at interface. Owing to diverse morphologies and interfacial interactions, the HNCs show excellent and unique properties that are absent in their constituents
