MICROPOROUS ARTICLES WITH A THREE-DIMENSIONAL POROUS NETWORK OF ACID-SINTERED INTERCONNECTED SILICA NANOPARTICLES AND METHODS OF MAKING THE SAME |
摘要 |
Articles are described including a first microfiltration membrane layer having a first major surface and a second major surface disposed opposite the first major surface, and a first silica layer directly attached to the first major surface of the first microfiltration membrane layer. The first silica layer includes a polymeric binder and acid-sintered interconnected silica nanoparticles arranged to form a continuous three-dimensional porous network. A method of making an article is also described, including providing a first microfiltration membrane layer having a first major surface and a second major surface disposed opposite the first major surface, and forming a first silica layer on the first major surface. |
