  • Publication number: 20120094036
    Abstract: This invention relates to coating compositions for thermal protection of substrates (particularly for protecting surfaces that are subject to transient, extreme temperature excursions), processes for manufacturing the coating and methods for applying them. The coating is designed to reduce/minimize the thermal diffusivity of the composite and uses constituent materials selected from groups of inorganic fibers, hollow microspheres, aerogels, and inorganic binders. Thermal diffusivity can be reduced/minimized by controlling the relative concentrations of the coating components.

  • Patent number: 5945084
    Abstract: This pertains to the general field of gels, foams, and aerogels, particularly, to low density open cell organic foams and low density open cell carbon foams, and methods for preparing them. These low density open cell organic foams are derived from organic gels which may be prepared from hydroxylated benzenes (such as phenol, catechol, resorcinol, hydroquinone, and phloroglucinol) and aldehydes (such as formaldehyde and furfural) using lower than conventional catalyst concentrations (e.g, an R/C value of greater than about 1000, yielding an initial room temperature pH typically lower than about 6.0). These organic foams are characterized by relatively large particle and pore sizes, high porosity, and high surface area. Low density open cell carbon foams derived from such organic foams are also shown, as are methods for preparing same. These carbon foams are also characterized by relatively large particle and pore sizes, high porosity, high surface area, and high electrical capacitance.
