摘要： Manufacturing a low-K dielectric organic/inorganic aerogel composite material and its application are provided. The manufacturing method comprises: (1) mixing; (2) hydrolysis; (3) condensation; (4) aging; (5) drying; (6) impregnating polymer solution; (7) phase separation and drying; and (8) cross-linking and curing. The manufacturing method can produce a low-K dielectric organic/inorganic aerogel composite material having a high strength. The low-K dielectric aerogel is in a porous structure, and its porosity is higher than 70% and its density is from 0.12 g/cm 3 to 0.42 g/cm 3 . The dielectric property of the low-K dielectric aerogel decreases along with an increase of its porosity, wherein a dielectric constant thereof is from 1.28 to 1.93, and a dielectric loss thereof is from 0.0026 to 0.014. The low-k dielectric aerogel can be used for a dielectric layer in a high-frequency circuit, an insulation layer in a semiconductor device or a microwave circuit in a communication integrated circuit.

摘要： Siloxane compounds are removed from the atmospheres by silica supporting an organic sulfonic acid compound. The silica with the organic sulfonic acid compound has a specific surface area down to 500 m 2 /g and up to 750 m 2 /g and a pore volume down to 0.8 m 3 /g and up to 1.2 m 3 /g, both measured by nitrogen gas adsorption method and has a pore diameter down to 4 nm and up to 8 nm, at the peak of differential pore volume measured by nitrogen gas adsorption method. The durability of gas sensing element against siloxanes is improved.

摘要： The present invention relates to a method for producing a silica aerogel and a silica aerogel produced thereby. More specifically, a first water glass solution is used to form a first silica wet gel, and then a second water glass solution is additionally added to form a second silica wet gel organically bonded to the first silica wet gel which serves as a basic skeleton, so that a silica aerogel with enhanced physical properties is formed to increase the resistance to shrinkage in ambient drying. Thus, a low-density silica aerogel may be formed, and the concentrations of the first and second water glass solutions may be adjusted to control the physical properties of the silica aerogel.
