金属有机框架(MOFs)的多功能性导致了在各种领域的突破性应用,尤其是在能源领域,环境,和可持续性。例如,MOFs可以设计用于高吸收有毒气体和污染物,例如CO2、NH3和SO2,但是由于这些分子的化学和物理性质的差异,设计显示对所有这些气体的有形吸收的单个MOF是具有挑战性的。为此,将多种MOF集成到纺织纤维上并制作各种结构已经成为关键的发展,增强框架的耐用性和可用性。在现成的纺织纤维上制备的MOF复合材料提供了关键应用所必需的灵活性,包括多相催化,化学传感,有毒气体吸附,和药物输送,同时保留了MOFs的独特特征。本研究介绍了一种可扩展且可适应的方法,用于使用浸涂方法将多个高性能MOF无缝嵌入到单个纺织纤维上。我们探索了这些多MOF复合材料对CO2,NH3和SO2的吸收能力,并观察到与传统粉末材料相似的性能。随着有害气体的吸附,我们还评估了这些MOF/纺织复合材料对化学战剂(CWA)如GD(索曼)的渗透和反应性,HD(芥子气),VX。在组合中,这些结果证明了在现实场景中建立一致的神经毒剂水解策略的根本进展.这种方法可以显著增加对CWA的保护,并增强防护装备如用于防护服的织物的有效性。这种用于在单个纺织纤维上集成多个MOF的浸涂方法释放了大量可能性,并为未来MOF基复合材料的部署创新铺平了道路。
The versatility of metal-organic frameworks (MOFs) has led to groundbreaking applications in a wide variety of fields, especially in the areas of energy, environment, and sustainability. For example, MOFs can be designed for high uptake of toxic gases and pollutants, such as CO2, NH3, and SO2, but designing a single MOF that shows tangible uptake for all of these gases is challenging due to the differences in the chemical and physical properties of these molecules. To this end, integrating multiple MOFs onto textile fibers and crafting various structures have emerged as pivotal developments, enhancing framework durability and usability. MOF composites prepared on readily available textile fibers offer the flexibility essential for critical applications, including heterogeneous catalysis, chemical sensing, toxic gas adsorption, and drug delivery, while preserving the unique characteristics of MOFs. This study introduces a scalable and adaptable method for seamlessly embedding multiple high-performing MOFs onto a single textile fiber using a dip-coating method. We explored the uptake capacity of these multi-MOF composites for CO2, NH3, and SO2 and observed a performance similar to that of traditional powdered materials. Along with harmful gas adsorption, we also have evaluated the permeation and reactivity of these MOF/textile composites toward chemical warfare agents (CWAs) like GD (soman), HD (mustard gas), and VX. In combination, these results demonstrate a fundamental advancement toward establishing a consistent strategy for the hydrolysis of nerve agents in real-world scenarios. This approach can substantially increase the protection toward CWAs and enhance the effectiveness of protective equipment such as fabrics for protective garments. This dip-coating method for the integration of multiple MOFs on a single textile fiber unlocks a wealth of possibilities and paves the way for future innovations in the deployment of MOF-based composites.
