    摘要： A method of preparing transparent or nontransparent silica aerogel granules. The method includes forming a granular wet gel by spraying a silica sol into alcohol, the silica sol being prepared by mixing a water glass solution or an opacifier-containing water glass solution with an inorganic acid solution, forming a granular alcohol gel through gelation aging and solvent substitution of the granular wet gel in alcohol, hydrophobically modifying the surface of the granular alcohol gel using an organic silane compound, and drying the surface modified gel at ambient pressure or in a vacuum. The method may prepare silica aerogel granules in a short period of time through heat treatment at a relatively low temperature and at ambient pressure or in a vacuum, thereby ensuring excellent economic feasibility, continuity and reliability, suited for mass production.

    摘要： The present disclosure relates to a thermal cracking resistant zeolite membrane and a method of fabricating the same. The method includes dissolving an alumina-based material, a silica-based material and sodium hydroxide in water to prepare an aqueous solution, stirring the aqueous solution to form a hydrothermal solution, preparing a slurry of zeolite seeds through wet-type vibration pulverization and centrifugal separation of zeolite powder, passing the zeolite seeds through a support by vacuum filtration such that the zeolite seeds can be infiltrated into an inner region of the support ranging from a depth of 3 μm to a depth corresponding to 50% of a total thickness of the support, and immersing the support into the hydrothermal solution for hydrothermal treatment to grow a dense zeolite separation layer not only on the surface of the support but also on the inner region thereof. The zeolite membrane prevents the occurrence of thermal cracking on the zeolite separation layer, thereby providing good thermal stability and separation performance during heating and at a target processing temperature.

    摘要： The present disclosure relates to the preparation of a polymer composite material for building air conditioning or dehumidification having superior water-adsorbing ability, durability and antibacterial properties by electro spinning. Specifically, the disclosed method for preparing a polymer composite material for building air conditioning or dehumidification includes: (S1) adding a crosslinking agent or a crosslinking agent and a porous filler for conferring durability and antibacterial properties into a hydrophilic polymer solution antibacterial properties to prepare a polymer composite material solution; (S2) electrospinning the polymer composite material solution to prepare a nanofiber sheet; and (S3) crosslinking the nanofiber sheet by heat-treatment. Since the disclosed polymer composite material for building air conditioning or dehumidification has superior antibacterial properties and excellent water-adsorbing ability and durability, the polymer composite material can perform dehumidification when used for air conditioning of a building, thereby reducing air conditioning load and improving energy efficiency. Further, through dehumidifying cooling, the high-efficiency polymer composite material can remove moisture from the hot and humid air in the summer, thus reducing air conditioning load by decreasing latent heat load and saving energy. In addition, the polymer composite material can be used in moisture-sensitive production processes, industrial applications requiring moisture control or protection from damage or corrosion by moisture to reduce moisture and provide dry air.
