Magnetic Nanoparticles and Polymer Nanocomposites: Fundamentals and Biological, Environmental and Energy Applications focuses on the manufacturing and design of innovative magnetic polymeric nanocomposite materials for a broad range of different applications. These materials have truly outstanding and sustainable properties unlike other composites because they are combined with both organic (polymer matrix) and inorganic (semiconductor nanoparticles) materials to form a sustainable composite material. The book's focus is on magnetic semiconductor and polymer nanocomposites made from bioresorbable and biocompatible polymers, modified with magnetic nanoparticles. This book provides detailed knowledge on the modern research application of magnetic semiconductor and polymeric nanocomposites that have tremendous commercial value. In addition, these nanocomposite materials are also a good source for the renewable energy-based industry.
