Nanolayered polymer films were used to construct materials whose properties mimic bio-optic systems found in nature. The nanolayered structures have the unique ability to control the index gradient profile in three dimensions.
Typical polyHIPE (porous polymers from high internal phase emulsions) have a cellular structure with volume fractions from 0.2 to 0.04, cell diameters from 15 to 25μm and intercellular pore diameters from 0.5 to 10μm. Unique interpenetrating polymer networks synthesized within the polyHIPE exhibited enhanced mechanical properties and an extended temperature range for damping. Hybrid polyHIPE that...
Films comprised of alternating elastomeric and glassy polymer layers with a layer thickness less than one-quarter wavelength of light exhibit a useful pressure dependent refractive index.
