**6. Conclusion**

Nanocomposites are versatile materials and are the current focus of research across the world. Different methods, for example, sol-gel, electrospinning, precipitation, melt mixing, solution mixing, *in situ* polymerization, *in situ* interactive polymerization, intercalation, melt intercalation, and template synthesis, are used for the synthesis of nanocomposites. The nanocomposites have unique electrical, thermal, and mechanical properties and hence are materials of choice in a variety of fields, for example, automotive industry, aerospace, semiconductor, electronics, and biomedical applications. Due to their light weight and broader mechanical strength, in the future, these materials will replace the metals and their alloys in different fields. Progress is going on for silicon-carbon nanocomposites for the manufacturing of lithium-ion batteries with greater performance output, nanotube-polymer composites for faster bone healing, polymers-based windmill materials for better performance, development of lightweight and efficient sensors, and development of magneto-fluorescent materials for better tumor imaging. Polymer nanocomposites are the material of choice for packaging companies in near future. The future challenge is to synthesize such materials that bear better material properties and price compatibility in comparison to existing materials.
