  • System, method, and coating for strain analysis
    Patent number: 6327030
    Abstract: The subject invention relates to a strain-sensitive coating, a strain measurement system, and a method to determine strains on substrate materials. In a preferred embodiment of the subject invention, the system includes a luminescent strain-sensitive coating and a strain field mapping system which can be used to create a strain map of the mechanical strain on a substrate material. The luminescent strain-sensitive coating of the subject invention is preferably a polymer-based coating, and can incorporate one or more luminescent compounds. The subject coating can be applied to produce a thin film on a substrate material, such as aluminum, steel, polymer, or composite. One or more characteristics of the luminescence emanating from the coating can then vary in relation to the strain on the substrate material.

  • Use of polymeric catalyst in synthesis of sol-gel derived ceramic materials
    Patent number: 5316695
    Abstract: Polymeric catalysts (e.g., polymeric acid catalysts such as poly(styrene)sulfonic acid) can be used in the synthesis of sol-gel derived ceramic materials from metal alkoxides, for example, organic/inorganic hybrid materials formed by reaction of a metal alkoxide and a reactive endcapped polymeric modifier. The use of a polymeric catalyst, rather than a conventional monomeric (inorganic or organic) acid catalyst, has a non-deleterious effect on the aging behavior and offers potential for control of rheological properties (spinnability, coatability, etc.) of the hybrid materials.
