Polymeric matrix materials for infrared metamaterials
| DWPI Title: Synthesizing low-loss polymeric matrix material for e.g. long wavelength infrared metamaterials, by partially hydrogenating unsaturated polymer comprising double or triple bonds, and depositing film of polymer and crosslinker on substrate |
| Abstract: A polymeric matrix material exhibits low loss at optical frequencies and facilitates the fabrication of all-dielectric metamaterials. The low-loss polymeric matrix material can be synthesized by providing an unsaturated polymer, comprising double or triple bonds; partially hydrogenating the unsaturated polymer; depositing a film of the partially hydrogenated polymer and a crosslinker on a substrate; and photopatterning the film by exposing the film to ultraviolet light through a patterning mask, thereby cross-linking at least some of the remaining unsaturated groups of the partially hydrogenated polymer in the exposed portions. |
| Use: The method is useful for synthesizing a low-loss polymeric matrix material for infrared metamaterials (claimed) such as long wavelength infrared metamaterials. |
| Advantage: The synthesized matrix material exhibits low loss at optical frequencies, facilitates the fabrication of all-dielectric metamaterials, provides excellent planarization to the infrared metamaterials, and has good thermo-mechanical and spectral properties. |
| Novelty: The method comprises: providing an unsaturated polymer comprising double or triple bonds; partially hydrogenating the unsaturated polymer; depositing a film of the partially hydrogenated polymer and a crosslinker on a substrate; and photopatterning the film by exposing a portion of the film to UV light through a patterning mask for cross-linking the remaining unsaturated groups of the partially hydrogenated polymer in the exposed portion. The step of providing the unsaturated polymer comprises a ring opening metathesis polymerization of norbornene. |
