Abstract
Packaging application of the materials require strong barrier as well as mechanical properties. Majority of the reports in the literature have studied the mechanical properties while neglecting the barrier properties and it is generally assumed that the improvement in mechanical properties leads to automatic enhancement of barrier performance. However, it may not be true in all the cases as the permeation properties are more sensitive to interface between the polymer and filler phases. The incompatibility between the filler surface modification and polymer or the presence of excess surface modification on the filler surface can negatively impact the permeation properties, while the mechanical performance may still enhance. The current chapter focuses on the two very important elastomeric materials used in large amounts in packaging industry. Various factors affecting the barrier performance have been quantified. Use of not only montmorillonite, but also vermiculite has been presented. The importance of clean filler surface on the composite properties has also been underlined. The determination of average aspect ratio as a tool to control or tune the microstructure and properties of the nanocomposites has been shown with the help of finite element computer models.
