Polymer Blend Nanocomposites for Energy Storage Applications presents the latest developments in polymer blend-based nanocomposites for applications in energy storage, covering theoretical concepts, preparation methods, characterization techniques, properties, and performance.The book begins by introducing polymer blend-based nanocomposites, preparation methods, mechanisms, requirements, theory, modelling, and simulation. The second part of the book explains the use of specific base materials, including elastomers, thermoplastics, thermoset polymers, and biodegradable polymers. The third and fourth sections of the book provide methodical coverage of polymer blend nanocomposites with different fillers, both for conducting polymers and non-conducting polymers. Subsequent chapters then guide the reader to specific devices, such capacitors, supercapacitors, batteries, fuel cells, and solar cells. Finally, other key aspects are considered, including the conversion from laboratory to industry, and recycling and life cycle assessment of polymer blend nanocomposites used in energy devices.This is a valuable resource for researchers and advanced students across nanotechnology, polymer science, composite science, surface science, chemistry, and materials science, as well as for scientists, engineers, and R&D, professionals with an interest in polymer nanocomposites for energy storage applications.
