Flexible surface-supported MOF membrane via a convenient approach for efficient iodine adsorption

Flexible surface-supported MOF membranes were successfully prepared on cloth by a simple method and used for iodine adsorption for the first time. CuAceAd crystals were synthesized and deposited in situ on the cloth at 50 ℃. The synthesis of the membranes proved to be robust, stable and consistent, as demonstrated by the SEM and XRD. The adsorption properties of the MOF membranes were measured in iodine vapor and iodine/cyclohexane solution, which showed a maximum iodine sorption capacity of 609.76 mg g −1 in the vapor and 144 mg g −1 in the solution, respectively. Additionally, the membranes displayed excellent regeneration ability. These results implied that the easy-obtained and environmental-friendly flexible MOF membranes have a great potential for engineering application in iodine adsorption.
