Research progress of MOFs-based multifunctional textiles
The textiles produced by the traditional textile industry have relatively single function and cannot meet the needs of modern people's life.At present,the ordinary fabrics exposed to strong ultraviolet rays,toxic chemicals,bacteria and other environments are not enough to fight against the infringement of these harsh environments,resulting in the scope of application being greatly reduced.To improve the protective performance of fabrics and expand the range of applications,it is usually necessary to carry out surface modification.Therefore,the development of multifunctional textiles to improve product grade and increase the range of applications is now a hot spot in the field of textile research.Metal-organic frameworks(MOFs)are a new type of nanoscale porous polymers,which form an open,crystalline skeleton with permanent pores by bridging strong coordination bonds with metals(clusters)as nodes and organic ligands as connectors.Under mild synthetic conditions,the composition and structure of MOFs can be precisely tuned to achieve their target functions by simple modifications of metal nodes or ligands.Compared with traditional porous materials,MOFs materials have the advantages of larger specific surface area,non-toxicity and low cost,and larger porosity.Some studies have incorporated MOFs materials into fiber matrices for special applications.However,the above studies prepared MOFs fiber composites only by simple mixing,the interaction between MOFs and fibers was poor,and the final products obtained could not achieve the desired morphology and structure.In addition,hydrolytic instability is one of the major drawbacks of several MOFs,and to solve these problems,the integration of MOFs onto fibers through covalent bonding and hydrophobic modification may be a feasible solution for the development of future MOF fabrics.Combining the advantages and defects of MOFs@fabrics,their preparation methods and application prospects are summarized,and the development prospects of researching MOFs@fabrics in developing multifunctional textiles such as long-lasting and high-value utilization are envisioned.Nowadays,the composite of MOFs materials onto fabrics has been realized by many people,and the main methods of loading MOFs particles onto fabrics are impregnation,radiation grafting,hot pressing,in-situ growth,and layer-by-layer self-assembly,and each method has its own advantages and shortcomings.We can choose the appropriate method through different application scenarios,and the synthesized multifunctional textiles have been developed in the areas of antimicrobial,chemical resistance,UV resistance,oil-water resistance,chemical contamination resistance,and oil-water resistance.The synthesized multifunctional textiles have good performance in the fields of antimicrobial,antichemical,anti-ultraviolet,oil-water separation and smart sensors.The treatment of metal-organic frameworks with anti-UV and anti-bacterial functions on textiles can give the textiles additional properties and construct rough surfaces for the textiles,creating conditions for the textile surfaces to obtain multi-functional properties.These multifunctional textiles can not only enhance their own grade and value,but also provide convenience for daily life.With unique advantages of the existence of a huge potential,they will occupy a place in the future market,and provide new ideas for developing green,energy-saving,efficient,economical and practical methods to build multifunctional textiles with stable performance and lasting functions,which has great research value and significance.
