ABSTRACT
This chapter discusses the development of nanocomposites alongside their performance ascertaining characterizations and breakthrough applications of recent origin. Among the preparation methods, there exist chemical and physical methods, making use of bottom-up and top-down principles. Some of the relatively less used methods for making MMNCs are melt falling drop quenching and one-step preparation of carbon dot and Au nanoparticle consisting NCs. Based on the exclusive results of characterization, different NCs are used for their specified applications. Characterization methods for NCs practiced significantly for NC characterization over the last decade include scanning electron microscopy, transmission electron microscopy, optical microscopy, and atomic force microscopy. Optical microscopy is significant in characterizing the macroscopic structures when the matrix is transparent and the sample is extremely thin. Nanocomposite packaging films bring about changes in the internal or external environment through oxygen impermeability attributes.
