This highlights ongoing research efforts on different aspectsof polymer nanocomposites and explores their potentials to exhibitmulti-functional properties. Inthis context, it addresses both fundamental and advanced concepts, whiledelineating the parameters and mechanisms responsible for these potentials. Aspects considered includeembrittlement/toughness; wear/scratchbehaviour; thermalstability and flame retardancy;barrier, electrical and thermal conductivity; andoptical and magnetic properties. Further, the book was writtenas a coherent unit rather than a collection of chapters on differenttopics. As such, theresults, analyses and discussions presented herein provide a guide for thedevelopment of a new class of multi-functional nanocomposites. Offering aninvaluable resource for materials researchers and postgraduate students in thepolymer composites field, theywill also greatly benefit materials
