Nanoporous ceramic membrane and preparation method thereof
A nanoporous ceramic membrane and preparation method thereof is provided. The nanoporous ceramic membrane is prepared by halloysite nanotubes (HNTs), and its porosity is between 35% to 85%. This method comprises steps as following: HNTs and polymers with a certain ratio are dispersed in organic solvent, and HNTs/polymer composite fibers are prepared through electrospinning method; after the HNTs/polymers composite fibers are laminated, they are sintered at high temperature in a certain or vacuum atmosphere, and a nanoporous ceramic membrane is obtained. Ceramic membrane prepared by this method is corrosion resistant, thermal resistant, and have large specific surface area, it may widely applied in the field of filtration, catalyst carrier and purification of high-temperature gas, etc.
