Abstract

This invention relates to a method of making perfluorinated elastomeric materials, and to materials made by such methods. In the full synthetic scheme, a partially fluorinated polymeric compound, with moieties to prevent crystallization, is created. It is then crosslinked to a desired degree, then perfluorinated. Various intermediate materials, such as partially fluorinated crosslinked polymers, have useful properties, and are or may become commercially available. One embodiment of this invention therefore relates to perfluorination of a selected partially fluorinated, crosslinked material, which is one step of the full synthetic scheme.

Method to synthesize lanthanide fluoride materials from lanthanide fluorinated alkoxides

Patent Boyle, Timothy J.

Lanthanide fluorinated alkoxide derivatives can be synthesized from the alcoholysis reaction of the lanthanide bis-trimethylsilyl amide and an excess amount of hexafluoro iso-propanol. Nanoparticles can be formed from the lanthanide fluorinated alkoxide derivatives by a solvothermal or solution precipitation process.

Fluorination of amorphous thin-film materials with xenon fluoride

Patent Weil, Raoul B [Haifa, IL]

A method is disclosed for producing fluorine-containing amorphous semiconductor material, preferably comprising amorphous silicon. The method includes depositing amorphous thin-film material onto a substrate while introducing xenon fluoride during the film deposition process.

Printing transferable components using microstructured elastomeric surfaces with pressure modulated reversible adhesion

Patent Menard, Etienne; Rogers, John A.; Kim, Seok; ...

In a method of printing a transferable component, a stamp including an elastomeric post having three-dimensional relief features protruding from a surface thereof is pressed against a component on a donor substrate with a first pressure that is sufficient to mechanically deform the relief features and a region of the post between the relief features to contact the component over a first contact area. The stamp is retracted from the donor substrate such that the component is adhered to the stamp. The stamp including the component adhered thereto is pressed against a receiving substrate with a second pressure that ismore » « less

Adhesive, elastomeric gel impregnating composition

Patent Shaw, David Glenn [Tucson, AZ]; Pollard, John Randolph [Tucson, AZ]; Brooks, Robert Aubrey [Tijeras, NM]

An improved capacitor roll with alternating film and foil layers is impregnated with an adhesive, elastomeric gel composition. The gel composition is a blend of a plasticizer, a polyol, a maleic anhydride that reacts with the polyol to form a polyester, and a catalyst for the reaction. The impregnant composition is introduced to the film and foil layers while still in a liquid form and then pressure is applied to aid with impregnation. The impregnant composition is cured to form the adhesive, elastomeric gel. Pressure is maintained during curing.

Elastomeric member and method of manufacture therefor

Patent Hoppie, Lyle O [Birmingham, MI]

An energy storage device (10) is disclosed consisting of a stretched elongated elastomeric member (16) disposed within a tubular housing (14), which elastomeric member (16) is adapted to be torsionally stressed to store energy. The elastomeric member (16) is configured in the relaxed state with a uniform diameter body section (74), and transition end sections (76, 78), attached to rigid end piece assemblies (22, 24) of a lesser diameter. The profile and deflection characteristic of the transition sections (76, 78) are such that upon stretching of the elastomeric member (16), a substantially uniform diameter assembly results, to minimize the requiredmore » « less
