  • Patent number: 6313219
    Abstract: The present invention provides a systematic method for “engineering” hybrid inorganic/organic compounds (IOCs) to exhibit specific physico-chemical properties as may be desired for a particular materials application. Such hybrid inorganic/organic compounds comprise, in some embodiments, an organic phase in the form of a polymer matrix and an inorganic phase that is chemically linked thereto. In one embodiment of the method, given a specific application, (i) desired physico-chemical properties to be possessed by the hybrid IOC are defined; (ii) candidate inorganic and organic phases are selected; (iii) the morphology of those phases is controlled via “microstructural engineering” such that the phases collectively exhibit the physico-chemical properties required of the hybrid IOC; and (iv) the morphology of the hybrid IOC is controlled via “macrostructural engineering” such that the physico-chemical collectively possessed by the phases are exhibited by the hybrid IOC.

  • Patent number: 6281271
    Abstract: The invention relates to a dental material with at least one polymerizable binder and at least one filler containing a redox-initiator system for the radical polymerization, which comprises an initiator and an activator. The material is characterized in that the filler contains a homogeneous mixture of a first part of the filler, which is mixed with the initiator, a second part of the filler, which is mixed with the activator, and a third part of the filler, which does not contain a component of the initiator system. The materials are particularly suitable as cements and filling materials.

  • Patent number: 5739180
    Abstract: Flat-panel displays, a substrate for use in such displays, and methods for making the displays and the substrate are disclosed. The substrate is a hybrid composite containing an organic component and an inorganic component. The substrate possesses attributes of the organic component, which is typically a plastic, such as light weight and impact resistance, as well as attributes of the inorganic component, typically silica particles, such as high temperature stability. A variety of flat-panel displays can be made by depositing appropriate device layers, using standard fabrication procedures, on the hybrid composite substrate. The monomer is selected, and the relative concentrations of the organic to the inorganic component in the composite are established, based on the thermal processing requirements for making the type of display for which the substrate is intended.
