Smart Functional Hybrid Nanocomposites: Fundamentals and Applications for Environmental Sustainability and Energy introduces readers to the fundamental principles behind these materials, covering their chemical and physical properties, synthesis methods, characterization techniques, and various applications. Modeling methods, approaches to tailoring their functional response, processing techniques (including additive manufacturing), and assessment techniques are each covered. Various applications are also discussed such as water purification, environmental remediation, energy harvesting and conversion, their use in light-emitting diodes, solar cells, photodiodes, field-effect transistors, and more. The book concludes with chapters outlining the sustainability, recyclability, and life cycle assessment of these materials, as well as current challenges and future directions associated with their use.
