Abstract
Lessons from biology have revealed that natural materials systems have hierarchical structures that are
specifically designed to accommodate a unique spectrum of required properties. These systems always
have many scale levels that are bound together by interfacial coupling or adhesion. Micro/nanolayered
coextrusion processing is highly suited to apply these lessons of scale, interaction and architecture. Three
examples will be discussed emphasizing scale in photonic applications with high refractive index contrast,
interfacial phenomena in amorphous systems, and polymer solid state structure and morphology obtained
by confined crystallization. With different amorphous polymers, the degree of segmental interdiffusion has
been quantitatively correlated with the thickness of the interphase region. This enables the establishment of
relationships between adhesion and various degrees of miscibility. Finally, unique single crystal with
lamellar orientation during confined crystallization, will be discussed which allows the development of
high barrier packaging systems.
