| Abstract | Unusual structures consisting of alternating stacks of 200 nm-thick nanoporous and 5 to 20 μm-thick pore-free layers were obtained with cyclo-olefin copolymer thin sheets. Such copolymer is well-known for its remarkable optical properties. The structural configurations induced during foaming provide high reflectivity in the visible spectrum along with partial transmittance in the UV and visible ranges depending on the microstructural characteristics of the porous layers. Adequate load applied to the sheet can nevertheless eliminate this reflectivity as these low-density foamed layers remain very pressuresensitive. It is postulated that the mechanisms leading to such an intriguing structure is related to a spinodal decomposition. |
