Preparation of asymmetric porous materials
| DWPI Title: Preparing asymmetric microporous material, comprises depositing microporous material film on flexible substrate and applying anisotropic stress to flexible substrate, where the microporous material film is formed of e.g. silica |
| Abstract: A method for preparing an asymmetric porous material by depositing a porous material film on a flexible substrate, and applying an anisotropic stress to the porous media on the flexible substrate, where the anisotropic stress results from a stress such as an applied mechanical force, a thermal gradient, and an applied voltage, to form an asymmetric porous material. |
| Use: The process is useful for preparing an asymmetric microporous material. |
| Novelty: Preparing an asymmetric microporous material, comprises depositing a microporous material film on a flexible substrate, and applying an anisotropic stress to the flexible substrate, where the anisotropic stress results from a stress of an applied mechanical force, a thermal gradient or an applied voltage, to form an asymmetric porous material, where the microporous material film is formed of a majority of a material of silica, alumina, aluminosilicate or titania. |
