<p>This book focuses on the preparation of polymer nanocomposites for various fields such as structural electronic sensing energy harvesting and biomedical applications. A wide variety of matrices have been considered such as polymer-modified asphalt ultra-high molecular weight polyethylene polymethyl methacrylate polydimethylsiloxane elastomer polyvinylidene fluoride polyvinyl amide poly(e-caloprolactone) and ureasyl polyether. The results corroborate that incorporating nanomaterials into polymeric matrices facilitates developing advanced materials with improved properties. Issues such as filler?matrix interactions molecular organization and rearrangement size-dependent functionality etc. are addressed in detail. Advanced nanosensing nanofabrication and nanocharacterization procedures are advantageously applied.</p>
