  • Publication number: 20100314587
    Abstract: The disclosure provides compositions prepared by combining nanomaterials with a halide-containing polymer, thereby forming a combined polymer matrix having dispersed nanomaterials within the matrix. The nanomaterials may be carbon-based nanotubes, in some applications. A halide-containing monomer is combined with nanotubes, and then polymerized in some compositions. In other applications, a halide-containing polymer is solution processed with nanotubes to form useful compositions in the invention. Also disclosed are probes for near field detection of radiation.

  • Publication number: 20060033087
    Abstract: The present invention is directed to a composite having tunable radiation diffracting properties which includes a flexible, water-free polymeric matrix and a crystalline colloidal array of particles having a lattice spacing, the array being embedded in the polymeric matrix and the lattice spacing changing responsive to stress applied to the polymeric matrix, thereby causing the radiation diffracting properties to change, wherein the polymeric matrix, the lattice spacing and the radiation diffracting properties all return to their original state essentially immediately upon removal of the stress. The present inventive composite is preferably made by a process, which involves forming a preliminary hydrogel polymerized crystalline colloidal array (PCCA), dehydrating the PCCA, and then forming a final, encapsulating polymeric matrix.

  • Patent number: 6953653
    Abstract: Optical waveguides interconnect optical information processing devices, or connect such devices with other optical communication links such as glass optical fibers. Fluoropolymers consisting of alternating perfluorocyclobutane and aryl ether linkages possess suitable properties for optical waveguides and other devices due to tunability in optical properties of the copolymers. Perfluorocyclobutane (PFCB) copolymer may be employed in solutions that exhibit a high solids content. Such solutions show useful physical properties for optical waveguide devices since the solutions are capable of achieving single step film thicknesses, when applied to a substrate, of greater than about 0.6 microns, and sometimes may achieve a thickness of 10 microns or more.

  • Patent number: 6696534
    Abstract: Fluoropolymers consisting of alternating perfluorocyclobutane and aryl ether linkages possess suitable properties for optical waveguides and other devices using refractive properties of the polymers. Perfluorocyclobutane (PFCB) polymers having aryl groups alternating on an ether chain have shown useful physical properties for optical waveguide applications. Processes for micromolding such polymeric films by replicating a pattern or image directly from a silicon master, rather than from a polydimethyl siloxane (PDMS) mold, are disclosed.
