Abstract

Plastics have been used extensively and exploited its usages in various applications such as packaging materials, automotive parts, tubes, pipes, and many more. The plastics have attracted many fields for its versatility, lightweight, and durability. Plastics are being used broadly as food packaging materials which come as bottle containers, food containers, and lightweight take-away food packets. However, as plastics are not degradable, they are causing a major environmental problem due to scarce of landfill sites. The plastics are also being washed into the sea and causing pollution in the ocean and being eaten by the fishes. Thus, there cause a need for developing biodegradable materials that have both mechanical strength and biodegradable. A lot of researchers are contributing to developing biodegradable materials that can substitute conventional polymers, however, there is still limit of mechanical strength and elongation-at-break as per need for food packaging. Therefore, the polymers/biodegradable polymers are being mixed with nano-sized fillers to form nanocomposites which have improved mechanical strength. In this chapter, preparations of nanocomposites are discussed thoroughly and the characterizations that are being used to study the properties of the nanocomposites are detailed in the sections below.
