  • Patent number: 6198216
    Abstract: An electroluminescent lamp is presented, wherein at least one of the phosphor layer or the dielectric layer comprises a polyureasilazane polymer. The polyureasilazane may be added to the fluoropolymer resin of the phosphor layer or the dielectric layer, and/or may be used to coat the phosphor particles within the phosphor layer or the inorganic filler particles within the dielectric layer. Use of polyureasilazanes confers enhanced adhesion and environmental resistance.

  • Patent number: 5922453
    Abstract: A ceramic-filled fluoropolymer composite is presented, suitable for use as an electrical substrate material. In accordance with the present invention, a ceramic-filled fluoropolymer composite further comprises high temperature, high modulus, finely powdered polymeric material. The median particle size of the finely powdered polymeric material is less than about 200 .mu.m. The finely powdered polymeric material is further stable at temperatures greater than about 350.degree. C. Substitution of the finely powdered polymeric material for fluoropolymer matrix material within a fairly narrow concentration range results in a composite with enhanced flexural modulus, but no deleterious effect on dielectric loss. The composite material is plated or clad with conductive material.

  • Patent number: 5358775
    Abstract: A high dielectric constant (K'.gtoreq.4), low thermal coefficient of dielectric constant (TCK'.ltoreq.150 ppm/.degree. C.) electrical substrate material comprises a fluoropolymer (preferably PTFE) filled with particulate ceramic material (powder) which exhibits low loss, comparatively high K' and acceptable TCK'. Examples of such ceramic powders include "class 1" capacitor ceramics. In accordance with an important feature of this invention, it has been discovered that it is insufficient to use only a low TCK' filler (e.g., class 1 capacitor ceramic powder) in the fluoropolymeric binder in order to achieve the desired TCK'. Instead, it has been discovered that the coefficient of thermal expansion (CTE) of the composite must also be sufficiently low (e.g.,.ltoreq.35 ppm/.degree. C.) to result in a composite which consistently maintains a low TCK'. This low CTE is achieved by adding one or more additional particulate ceramic fillers.
