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/cm3 to 0.45 g/cm3. 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 1.89, and a dielectric loss thereof is from 0.052 to 0.023. 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： The invention provides a method for producing a heat insulating material composed of a hydrophobic aerogel, and the method includes the steps of: (1) mixing step; (2) hydrolysis step; (3) condensation step; (4) aging step; and (5) drying step. In the method, a siloxane compound, an inorganic gel, and a halogen-free surfactant are mixed and then a sol-gel process is performed to produce the aerogel heat-insulating material without water-washing. The produced heat-insulating material has preferable strength, smooth appearance, and low shrinkage and can overcome the powder-dropping problem. By the provided method, an aerogel heat-insulating board can be produced, or an aerogel cold-resisting and heat-insulating blanket can be produced by mixing with a fiber or a foam material.

摘要： A method for producing an aerogel granule having a hydrophobic-hydrophilic bipolar core-shell structure combines an aerogel precursor having a hydrophilic structure with another aerogel precursor having a hydrophobic structure. The method comprises the steps of: mixing a hydrophilic alkoxysilane compound, a hydrophobic alkyl-substituted alkoxysilane compound, and an organic solvent to form a mixture; adding an acidic catalyst to the mixture to perform hydrolysis; adding a basic catalyst to the hydrolyzed mixture to perform condensation, and during the condensation adding a dispersion solvent to the hydrolyzed mixture and stirring the hydrolyzed mixture to gelate so as to form the aerogel granule having a hydrophobic-hydrophilic bipolar core-shell structure.
