  • Patent number: 7038357
    Abstract: A transducer is designed and fabricated using stretched rolled electroactive polymers. The invention includes the design, fabrication, and integration of a stretched rolled actuator system with corresponding sensing, control and power subsystems. The invention presented is based on the improved performance of electroactive polymer transducers that can be achieve by prestretching the polymeric material. In this invention, the preferred stretch is maintained in a rolled configuration by introducing structural elements to the transducer. The structural elements facilitate fabrication of the transducer as well as provide a compact and efficient means of maintaining stretch and the desired boundary conditions on the electroactive polymer during operation. These conditions together are used to improve and tailor the strain response of the transducer.

  • Patent number: 6974618
    Abstract: An optical data storage device comprised of periodic nanostructured polymer-based material produced from core-shell particles containing one dye in the core and a second dye in the shell. The combinations of dyes can be UV-Vis-dyes or Vis-NIR or UV-NIR. It is shown that selective single-photon photobleaching of the two dyes leads to increase in density of data storage and allows one to employ single-photon photobleaching to achieve the same storage density as in two-photon-writing.

  • Patent number: 6531558
    Abstract: The present invention provides new fluoromonomers having the generic structure: CF2═CF(OCH2CH2)nOR where n is an integer and R is a functional group and methods for producing same. A new method of synthesizing the fluoromonomers is provided. The present invention also relates to new fluoropolymers prepared from any one or combination of the new fluoromonomers and having the generic structure: —[—CF2CF{(OCH2CH2)nOR}—]m— where n is an integer, m is an integer and R represents an unsubstituted or inertly substituted hydrocarbyl group. The method also relates to new copolymers or terpolymers prepared from the new fluoromonomers alone, the new fluoromonomers and existing fluoromonomers or the new fluoromonomers and existing hydrocarbon or functionalized hydrocarbon monomers.
