This research aims to study processing--solid state structure--                 property relationships in microlayer (50 to 1000 layers)                        polymeric composites.  Dow coextrusion technology will be used                  for the production of microlayer systems.  Polymers of widely                   dissimilar solid-state structures and properties will be combined               into microlayer structures, thereby producing a composite system                with the desirable features of each component.  In some                         instances, further property enhancement will be achieved by                     uniaxial and biaxial orientation in a post-processing procedure.                The complex behavior of these composite systems will be analyzed                in terms of heirarchical levels of structure.  The dependency and               evolution of properties from these interactive hierarchical                     levels will be elucidated.  In particular, the effects of layer                 thickness and adhesion between layers will be analyzed.                         Polymeric materials selected for this study are chosen with                     attention to unique advantages that are achievable with the                     microlayer process.  Tough structures with coupled properties,                  such as selected light transmission or shielding, differential                  barrier and transport properties or piezoelectric response, will                be investigated.  By using microlayer processing of highly                      dissimilar polymers in combination with the hierarchical approach               to solid-state structure and property analysis, a new class of                  polymeric composite systems will be examined.
