6.1 Introduction

Recently researchers are working very diligently to provide a sustainable environment and have replaced synthetic polymers by using natural biopolymers. Using advanced technologies, composites of biopolymers and grafted biopolymers can be synthesized. These functionalized materials can be used for various applications due to their at-par performance as compared to synthetic polymers. The use of grafted biopolymers has rapidly increased over the last many years due to their versatile applications in day-to-day life. Natural polysaccharides have enormous advantages over synthetic polymers since they are easily available, nontoxic, and cost-effective. However, there are a few disadvantages of the natural polysaccharides such as, they are sensitive to temperature, easily contaminated by microbes, their viscosity gets lowered during storage, and are extremely sensitive to highly stressful conditions [1]. These limitations of natural polysaccharides can be overcome by modifying them, e.g., cross-linking [2], etherification [3], derivatization of functional ...
