Chemistry of High-Energy Biopolymer-Based Nanocomposites brings together the latest research in energy-rich and high-energy nanocomposites based on polysaccharide- and other biopolymer-based fillers with synthetic polymers, examining chemistry, properties, preparation and advanced applications. The book begins by explaining the fundamentals of bionanocomposites, the use of cellulose, cellulose derivatives, and lignocellulose as fillers, the chemistry of energy-rich polymer bionanocomposites, and the design of composite architectures. Innovative methods in chemical modification, characterization, and analysis, are then presented in detail, including scattering studies, Fourier infra-red spectroscopy, thermogravimetric analysis, differential scanning calorimetry, mechanical properties, microscopy studies, and rheological studies. This is followed by chapters focusing on specific properties and cutting-edge areas of application, including fire retardancy, electro properties, capacitors for energy storage, and cellulose and synthetic polymer blends as nanocomposites for auxiliary solid fuel. Finally, the book reviews recycling of biopolymer-based nanocomposites, the energy rich concept driving the bionanocomposites approach, and future perspectives and outlook.
