Advances in Bionanocomposites: Materials, Applications, and Life Cycle brings together the latest research in bio-based nanocomposites, with a strong emphasis on improved sustainability in terms of preparation, lifecycle and end applications. The book begins by introducing biopolymers, bionanocomposites and the latest methods for their synthesis, processing and characterization. Other sections focus on specific bio-based materials, including bionanocomposites based on polylactic acid, poly(vinyl alcohol), chitosan, starch, cellulose, and protein. A range of advanced applications are then introduced across 3D printing, high entropy alloys, wastewater remediation, agriculture, biomedicine, solar cells, electrochemical sensors, and packaging. Throughout the book, opportunities for improved sustainability are analyzed and highlighted. The final section brings this together with in-depth coverage of biodegradation, lifecycle, environmental impact, circular economy, economic considerations and future opportunities in bionanocomposites. This is a valuable resource for researchers, advanced students, R&D professionals, and industrial scientists from a range of disciplines.
