Polymer-clay nanocomposites have emerged as a new class of materials which have attracted considerable interest in research and development since polymer-clay nanocomposites have attained some enhancement compared to pure polymers.These new materials will enable the circumvention of classical material performance trade-offs by accessing new properties and exploiting unique synergism between materials that only occur when the length-scale of morphology and the fundamental physics associated with a property coincide on the nanoscale.Polymer-clay nanocomposites exhibit remarkable improvement in materials properties such as high dimensional stability,increased heat resistance,increased strength and modulus and deceased gas permeability compared to pure polymers.This book investigates the value-added properties of polymer-clay nanocomposites compared to pure polymers. The value-added properties for polymer-clay nanocomposites make them useful in industries such as:Automobiles,Construction, Aerospace,Electrical and Electronics and Food Packing or for everyone in academia to explore through research the usefulness of these properties enhancement of polymer-clay nanocomposites to industry
