(536c) Emulsion Templated Polymers As Structured Supports for MOF Adsorbents
We have successfully incorporated the MOF UiO-66-NH2 into a 2-hydroxyethyl methacrylate polyHIPE crosslinked with N,Nâ-methylene bisacrylamide. The porous structure of the polyHIPE has been preserved despite the incorporation of MOF particles. While the lower than expected BET surface areas of the composites suggested that the MOF was obstructed by the polymer, CO2 adsorption was not negatively affected at low pressures suggesting that the MOF is accessible to adsorbates even within the polymer. Dye uptake confirms this in the aqueous phase. The MOF-polyHIPE composites show promise as adsorbents for both gases and liquids, with the polymer enhancing the structural stability of the MOF and allowing the creation of three dimensional monoliths rather than powder or pellets.
