Colorometric detection of water using MOF-polymer films and composites
| DWPI Title: Manufacturing method of porous metal organic framework (MOF), involves detecting color change of first mixture and second mixture in presence of predetermined molecular species |
| Abstract: A method including exposing a mixture of a porous metal organic framework (MOF) and a polymer to a predetermined molecular species, wherein the MOF has an open metal site for the predetermined molecular species and the polymer has a porosity for the predetermined molecular species; and detecting a color change of the MOF in the presence of the predetermined molecular species. A method including combining a porous metal organic framework (MOF) and a polymer, wherein the MOF has an open metal site for a predetermined molecular species and the polymer has a porosity for the predetermined molecular species. An article of manufacture including a mixture of a porous metal organic framework (MOF) and a polymer, wherein the MOF has an open metal site for a predetermined molecular species and the polymer has a porosity for the predetermined molecular species. |
| Use: Manufacturing method of porous metal organic framework (MOF). |
| Advantage: The simple visual indicator is highly desirable. The thin films and the surfaces of powders change color within seconds of exposure to atmospheric water, since its reaction with water is extremely rapid. |
| Novelty: The method involves exposing a first mixture of a first porous metal organic framework (MOF) and a first polymer and a second mixture of a second porous MOF and a second polymer to a predetermined molecular species. Each of the first MOF and the second MOF has an open metal site for the predetermined molecular species and each of the first polymer and the second polymer has a different permeability for the predetermined molecular species. A color change of the first mixture and the second mixture is detected in the presence of the predetermined molecular species. |
