Caveats<br />
Issues are not new Issues are not unique<br />
Critical Aspects:<br />
• Polymer NanoComposites?<br />
Is this a „reinvention‟ of filled <strong>polymer</strong>s?<br />
• Hierarchical morphology – property correlations?<br />
When is this not an issue?<br />
• Confined <strong>polymer</strong> behavior?<br />
Different from thin film <strong>and</strong> coating technology?<br />
• Filler impact <strong>polymer</strong> meso phase?<br />
Crystallization aids & process dependent crystal fraction?<br />
Preponderance of interface 700 m 2 /g<br />
Diminishing small volume fraction of „bulk‟ d ~ Rg<br />
Aspect ratio of constituents a > 100<br />
Dissimilar mechanical <strong>properties</strong> Ef/Em ~ 10 3<br />
Hierarchical morphology has one more scale CF(nm-mm; q)
