ABSTRACT
Biopolymers are recognized as promising candidate materials for diverse field applications due to their outstanding physical, chemical, and mechanical properties. This chapter describes various classifications of biopolymers, from natural to synthetic, according to their chemical characteristics. Apart from that, it discusses various applications of biopolymers in different fields such as medicine, drug delivery, and other facets. The chapter gives a summary of the future directions for sustainable future with polymer industries. Biopolymers are classified into two major categories: natural and synthetic biopolymers. The advance in technology gives rise to new polymer complexes with unique properties in the desired applications of polymer engineering. The innate ability of many scientists to work on specific parts such as structural, mechanical, and biochemical parts led to the discovery of cellulose, chitosan, starch, PHAs, etc., and their synthesis.
