中文摘要:

      金属-有机框架（MOFs）是由金属离子和有机配体构成的具有一维、二维、三维结构的多功能晶态材料，MOFs本身的晶型结构决定了它们大多以粉末状存在，在回收、加工成型等方面受到限制。选择天然的或改性的柔性纤维素基材作为沉积MOFs的理想基底，一方面MOFs可赋予纤维素基材许多新的功能，实现纤维素的高值化利用；另一方面纤维素基材可为MOFs提供更广阔的利用空间，实现MOFs的多级开发利用。本文综述了MOFs/纤维素复合材料的研究进展，包括基底材料的选择、制备方法、性能及应用等。

Abstract:

      Metal-organic frameworks （MOFs）， composed of metal ions and organic ligands， are multifunctional crystalline materials with one-dimensional， two-dimensional， and three-dimensional structures. The crystalline structure of MOFs renders their existence mainly as powder， limiting their recycling， processing， and molding. Therefore， natural or modified flexible cellulose substrate is chosen as the ideal base material for MOFs deposition， in which， MOFs can endow cellulose substrate with many novel functions to realize its high-value utilization； cellulose substrate can provide MOFs more room for application to realize its multi-level development and utilization. The research progress on MOFs/cellulose composites was reviewed in this paper， including selection of base materials， preparation methods， properties， and applications， etc.
