  • Patent number: 9868844
    Abstract: The present invention provides materials and methods to enhance dispersion of carbon black within polymer systems, improving both static physical properties and dynamic physical properties of polymers (such as natural or synthetic rubber) containing carbon black. Some variations provide a composition containing a polymer, carbon black, and a performance-enhancing additive comprising amorphous silica, wherein the performance-enhancing additive causes a property improvement associated with or imparted by the carbon black. The performance-enhancing additive scrubs or exfoliates the carbon black in situ, to improve tensile strength, modulus, tear, elongation, dispersion, flow properties, viscosity, hardness, specific gravity, rebound, torque, and/or load of the polymer composite.

  • Patent number: 9834687
    Abstract: A nano-composite material for coating glass, as well as methods of its manufacture and use, are disclosed. The composite may be composed of a first metal oxide bridging a silicone oil moiety and an anionic surfactant moiety, and a second metal oxide bound to the silicone oil moiety. The composite may be fabricated by heating a first metal oxide and a second metal oxide with silicone oil, followed by the addition of a mixture of the surfactant and an oxidizing solution. The composite may be mixed with a suitable solvent and applied to a hot glass sheet. A glass coated with such a composite may transmit visible light, absorb some ultraviolet light, and reflect some near infrared light. The optical characteristics of the coated glass may be used to reduce heat in a glass-enclosed area by reducing the amount of infrared and ultraviolet light transmitted through the glass.

  • Patent number: 9828251
    Abstract: Silica aerogels with improved properties are disclosed together with methods for synthesizing such aerogels. The improved properties include lower thermal conductivity (better insulating capacity), lower acoustic velocity, lower dielectric constant and improved ductility. Greater tunability of the refractive index can also be achieved. The silica aerogels are prepared by a sol-gel processing method that provides better control of the formation or aerogel structures. Generally speaking, the improvements arise from control of the synthesis to create a morphology of primary clusters and diverse-sized secondary clusters of dense silica aerogels separated by less densely packed regions. By providing a broader range of secondary clusters and/or pore sizes and loose connectivity between clusters, reductions can be achieved in thermal conductivity and flexural modulus.
