Some embodiments of the invention provide a hydrophobic silica aerogel having advantageous properties, such as desirable performance on visible transmission, haze, or both.

The invention provides silica wet gel, silica aerogel, and methods that can be used to form an enhanced silica aerogel sheet having fewer optical defects along with other desirable properties.

A composite insulation assembly, including: (a) a bottom insulation layer, (b) a fiber supported aerogel blanket on top of the bottom insulation layer; and (c) a top insulation layer.

The present invention provides compositions and methods related to aerogel materials, including polyimide-based aerogels. In particular, aerogel materials optimized to have certain physical and chemical properties such as flexural and compressive strength are provided. In some embodiments, the aerogel materials can be at least partially carbonized.

The invention provides a coating material structure, including a packaging main body; and the packaging main body includes: a heater, an inner layer and an outer layer, wherein the heater is arranged inside the packaging main body to heat a pipeline; the inner layer is arranged between the pipeline and the heater, which has an inner flame-resistant layer; and the outer layer is arranged on outer surface of the heater for heat preservation and improves the working efficiency of the heater. By sandwiching the heater with the inner layer and the outer layer, the generated particles will not escape into the environment when the heater causes the insulating layer cracks or volatiles appear, thereby reducing environment dust. Moreover, the inner flame-resistant layer does not produce particles and volatiles when below the operating temperature. The inner flame-resistant layer can also be directly used as an insulating layer.

This thermal insulation material is provided with: thermal insulation layers, each of which has a porous structure having a skeleton that is composed of a plurality of particles connected with each other, while having pores inside and hydrophobic portions at least on the surface among the surface and the inside; and a pair of functional layers which are arranged on both sides of the thermal insulation layers in the thickness direction. The pair of functional layers have the same properties that include at least one of fire resistance and radiant heat dissipation properties.

A tempered glass for preventing generation of a rainbow pattern and a manufacturing method thereof are provided. The tempered glass for preventing generation of the rainbow pattern is prepared by compounding a protective layer and an ultra-low phase-difference substrate layer. A compounding process is introduced in the manufacturing method to allow the synchronous stretching of a plurality of layers. In the tempered glass, a substrate layer with an ultra-low phase difference in terms of a polarization angle from a polarizer is arranged, such that a user can well view a screen of an electronic product in various scenarios, and a content of a screen will not undergo rainbow patterns or color differences due to different scenarios and conditions. A material used for the tempered glass has a high light transmittance, a low haze, a high deformation rate, and a high resilience rate to allow ultra-high performance.

A composite material having a function of isolating heat and combustion supporting gases is disclosed. A layered structure of the composite material includes a carbon-silicon foam layer, a first acrylic resin layer, a glass fiber cloth layer, a second acrylic resin layer, a first silicone layer, a carbon fiber layer, a second silicone layer, a quartz wool layer, and a third silicone layer. Due to the layered structure of carbon-silicon foam material, glass fiber cloth, carbon fiber and quartz wool, the composite material can provide functions such as heat insulation, combustion-supporting gases insulation, heat conduction, and anti-breakdown for protecting lithium-ion batteries from thermal runaway.

The present invention provides compositions and methods related to aerogel materials, including polyimide-based aerogels. In particular, aerogel materials optimized to have certain physical and chemical properties such as flexural and compressive strength are provided. In some embodiments, the aerogel materials can be at least partially carbonized.

A composite insulating material includes two or more blankets, each having a substrate for a blanket and aerogel formed on the inside and a surface of the substrate for the blanket, and a super absorbent polymer layer including super absorbent polymer particles located between the blankets.
