Natural Polymers in Sustainable Materials: From Biopolymers to Green Composites

Author(s): Qingsong Zhu *

Natural polymers have emerged as crucial components in the development of sustainable materials due to their biodegradability, abundance, and versatility. Derived from renewable resources such as plants, animals, and microorganisms, natural polymers like cellulose, chitosan, starch, and proteins are increasingly being applied in packaging, medicine, and environmental technologies. Recent advances in materials science have extended their applications through chemical modification and the development of green composites reinforced with natural fibers or nanoparticles. This article highlights the role of natural polymers in advancing sustainable materials, emphasizing their structural diversity, performance, and contribution to circular economy strategies.
