用简单的方法成功地在布上制备了柔性表面支撑MOF膜，并首次用于碘吸附。合成了CuAceAd晶体，并在50摄氏度的温度下原位沉积在布上。经扫描电镜和x射线衍射分析证实，所合成的膜坚固、稳定、一致。对MOF膜在碘蒸气和碘/环己烷溶液中的吸附性能进行了测试，结果表明MOF膜在碘蒸气和碘/环己烷溶液中的最大碘吸附量分别为609.76 mg g（-1）和144 mg g（-1）。此外，该膜表现出良好的再生能力。这些结果表明，制备方法简单、环境友好的柔性MOF膜在碘吸附方面具有很大的工程应用潜力。
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 celcius. 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.
