Abstract
A method of electrophoretic deposition of adsorbent media onto an electrically conducting substrate. The adsorbent media may include one or more porous coordination polymers and/or one or more secondary adsorbing particles. The adsorbent media may be continuously applied from a liquid composition at a selected thickness and at a controlled rate and as a function of voltage profiles.
Claims13
A method of forming an adsorbent media coating comprising:
- drawing an electrically conductive substrate through a bath including a polar solvent and a metal salt present in said polar solvent;
- applying an electrical potential and depositing adsorbent material onto said conductive substrate, wherein said adsorbent material comprises one or a plurality of porous coordination polymers and one or a plurality of secondary adsorbing particles wherein said one or plurality of porous coordination polymers is present in said polar solvent at a concentration in the range of 0.1 g/L to 10 g/L and said one or plurality of secondary adsorbing particles are present in said polar solvent at a concentration in the range of 0.1 g/L to 10 g/L and said adsorbent material forms a coating having a thickness of 1.0 micron to 100 microns and said porous coordination polymers have a porosity of 1.0 μm to 100 μm.
