Cellulose is a natural biopolymer—the primary structural component of plant cell walls—composed of glucose units linked in linear chains. It is widely used in paper, textiles, and films due to its abundance, biodegradability, and tunable mechanical properties through chemical modification (e.g., cellulose acetate, viscose, microcrystalline cellulose). Engineers select cellulose and its derivatives when sustainability, renewability, and moderate stiffness are priorities, or when compatibility with water-based processing and natural-fiber reinforcement are required; variants also serve in food, pharmaceutical, and cosmetic applications where non-toxicity and biocompatibility are essential.
