Production of Ceramic Metal Oxide Membranes by Means of Reactive Electrospinning |
摘要 |
Traditionally, the manufacturing of ceramic metal oxide membranes is often expensive and extremely labor intensive due to the often necessary post-processing steps. The present invention discloses to a novel single-step process, to produce ceramic metal oxide membranes. More specifically, this invention relates to reactive electrospinning where a sol-gel solution containing alkoxides is electrically charged and formed a Taylor cone at the tip of a needle in an environment controlled chamber, and the Taylor cone rejects a continuous stream of alkoxide nanofibers which polymerized to form a ceramic metal oxide membrane (with and without a polymer substrate present). The manufactured membranes may be used for various applications, including dye sensitized solar cells and for carbon dioxide capturing. |

1. A method for manufacturing ceramic metal oxide membranes by electrospinning comprising:
applying an electric voltage to a sol-gel solution wherein the sol-gel solution comprising a solvent, at least one metal alkoxide, and at least one polymer; jetting the sol-gel solution an electrode collector in a controlled environment with a pre-determined humidity, wherein the metal alkoxide hydrolyzed into a metal oxide, the solvent vaporizes, and a condensation reaction occurs that results in the polymerization of the metal oxide. |
