The intention of this book is to provide an updated view of the synthesis, characterisation and applications of different kinds of nanocomposites. It includes 9 review chapters and 8 research chapters. The review articles introduce various nanocomposites like polymer-based nanocomposite (polymer-based carbonaceous nanocomposites, chitosan-quantum dots nanocomposites and chitosan-based inorganic nanocomposites), UV-cured nanocomposite coatings, carbon dots nanocomposites, layered double hydroxides/organo nanocomposites, catalytic membranes loaded with nanocomposite materials and block copolymer nanocomposites. The research articles include studies on the influence of silica nanoparticles on functional properties of polyurethane nanocomposites, the annealing effects in nanostructured carbon-copper films, fabrication, characterisation and modelling of functionally graded synthetic graphite/polymer nanocomposites, the mass transfer process in metal-ion exchanger nanocomposites, mechanosynthesis of Fe-MeC (Me=V, Ti, Nb) nanocomposites, preparation and adsorption for Congo red of rectorite/chitosan nanocomposite, synthesis, assembly, and performance of metal-oxide based nanocomposites using polyol technique and electrospinning and also synthesis and applications of developed metal matrix/nanodiamond composites. According to this book, you can get a comprehensive understanding about the development of nanocomposites in recent years. Moreover, you can figure out detailed synthesis methods as well as advanced characterisation methods for nanocomposites. It will be an inspiration for applications of nanocomposites in various fields. By covering both the fundamentals and synthetic applications, it is therefore suitable for both new and experienced researchers, chemists, biochemists, natural product chemists and graduate students.
