Process for the rapid development of high content metal-organic framework hollow fibers for gas separation and toxic chemical removal

Abstract

A process for the rapid fabrication of a sorbent hollow fiber membrane (HFM) with a very high metal organic framework (MOF) content as well as the apparatus to contain such fibers for the purposes of sequestering and separating chemicals is described. Herein we developed a process to rapidly prototype meters long HFM batches with a high MOF content for sequestering and filtration. The HFM produced herein can be tailored to precisely sequester chemical of a hazardous nature which may include chemical warfare agents (CWA) or toxic industrial chemicals (TIC). The HFM are comprised of a polymer-based material that includes a polymeric binder; and one or more porous active materials that adsorb, chemisorb, decompose, or a combination thereof, a hazardous chemical.
