摘要： A method is provided for making a porous inorganic membrane by using a mixture of an inorganic material, organic polymer particles and a solvent to form a slurry, the particles being non-spherical, distributing the slurry onto a surface, drying the slurry to remove the solvent and firing the dried slurry to produce the porous inorganic membrane. Examples of organic polymer particles include particles of acrylic. A substrate with a porous inorganic membrane disposed on the substrate is also provided, the inorganic membrane having an average thickness of from about 0.5 micron to about 30 microns, a porosity of from about 30% to about 65%, a median pore size (d50) of from about 0.01 micron to about 1 micron, and a value of (d90−d10)/d50 less than about 2, as measured by mercury porosimetry. An example of a substrate includes an inorganic porous support.

The composite molecular sieve membrane includes a support layer and a molecular sieve membrane layer, wherein the support layer is a high-porosity and porous ceramic which is made of nano- or submicron ceramic powder materials or ceramic material precursors prepared through an electrospinning process. The high-porosity and porous ceramic, is adjustable from 40% to 83%. The composite molecular sieve membrane of the embodiments uses the porous ceramic prepared through an electrospinning process as the support layer, and the support layer has a flat and continuous surface, high porosity, uniform and adjustable pore sizes, low-tortuosity pore channels, and high mechanical strength; the flux of the composite molecular sieve membrane is increased, besides, the seed crystals can attach effectively due to the fibrous pore channels of the support layer, ensuring the adhesion amount of seed crystals.

摘要： This invention discloses a method for preparing an antibacterial and dust-removal membrane. The method comprises the following steps: depositing a layer of nano-ZnO on the immersed membrane surface as the seed crystal with the atomic layer deposition instrument (ALD instrument); vertically immersing the membrane covered with nano-ZnO layer in a hydrothermal reactor filled with crystal growth solution, heating it for a period of time, taking the membrane out and cooling it to the room temperate, and removing it from the substrate; finally, heating this membrane in a drier, and purging it with nitrogen to remove the paraffin within the membrane pore to obtain the porous membrane with nano-ZnO arrays growing on the surface.
