Abstract

Metal-organic frameworks (MOFs) and hydrogels have abundant pores, creating much potential for applications in water purification, organic dye adsorption, and so on. In this study, polyvinyl alcohol (PVA) or PVA/chitosan (CS) hydrogel tubes containing in-situ synthesized MOF particles were facilely synthesized, which are capable of removing dyes from flowing fluids. The state of polymer chains during synthesis has a significant impact on microstructures and properties of obtained MOF/hydrogel composites. Hierarchical pores and polar groups endow such devices with good adsorption performance. Besides, a tubular MOF/hydrogel device was found to display excellent flexibility and stability, in which brittle ZIF-8 particles were surrounded and protected by the soft hydrogel matrix effectively. This work supplies a facile and novel strategy to prepare soft MOF/hydrogel tubes for adsorption of pollutants as well as for other potential applications.

通过在水凝胶中方便地原位合成金属-有机骨架颗粒获得管状吸附装置

金属有机骨架（MOFs）和水凝胶具有丰富的孔隙，在水净化、有机染料吸附等方面具有很大的应用潜力。本研究制备了聚乙烯醇（PVA）水凝胶管或聚乙烯醇/壳聚糖（CS）水凝胶管，该水凝胶管含有原位合成的MOF颗粒，能够去除流动流体中的染料。聚合物链在合成过程中的状态对制备的MOF/水凝胶复合材料的微观结构和性能有重要影响。层次化的孔隙和极性基团赋予了该装置良好的吸附性能。此外，发现管状MOF/水凝胶装置具有优异的柔韧性和稳定性，其中脆性的ZIF-8颗粒被柔软的水凝胶基质有效地包裹和保护。这项工作提供了一种简单而新颖的策略来制备软MOF/水凝胶管，用于吸附污染物以及其他潜在的应用。
