Development of Biodegradable Polymers Using Green Nanotechnology

Biodegradable polymers are a promising solution due to their environmentally-friendly nature and natural origin. Owing to challenges such as limited mechanical and barrier properties and extremely high production costs, their applications have remained restricted. Green nanotechnology, the integration of green chemistry and nano-scale engineering, provides novel prospects for enhanced functional performance of biodegradable polymers. This paper reviews preparation, characterization, and applications of biodegradable polymer nanocomposites prepared by green nanotechnology techniques. It features the use of natural nanofillers, natural-source solvents, and environmentally-friendly preparation techniques such as in situ polymerization and solvent casting. Recent advances, case studies, and future prospects for biodegradable polymer nanocomposites in packaging, agriculture, and biomedical applications are also discussed.
