Development\nof a Multiparticulate Metal–Organic\nFramework/Textile Fiber Swatch

The\nversatility of metal–organic frameworks (MOFs) has led\nto groundbreaking applications in a wide variety of fields, especially\nin the areas of energy, environment, and sustainability. For example,\nMOFs can be designed for high uptake of toxic gases and pollutants,\nsuch as CO<sub>2</sub>, NH<sub>3</sub>, and SO<sub>2</sub>, but designing\na single MOF that shows tangible uptake for all of these gases is\nchallenging due to the differences in the chemical and physical properties\nof these molecules. To this end, integrating multiple MOFs onto textile\nfibers and crafting various structures have emerged as pivotal developments,\nenhancing framework durability and usability. MOF composites prepared\non readily available textile fibers offer the flexibility essential\nfor critical applications, including heterogeneous catalysis, chemical\nsensing, toxic gas adsorption, and drug delivery, while preserving\nthe unique characteristics of MOFs. This study introduces a scalable\nand adaptable method for seamlessly embedding multiple high-performing\nMOFs onto a single textile fiber using a dip-coating method. We explored\nthe uptake capacity of these multi-MOF composites for CO<sub>2</sub>, NH<sub>3</sub>, and SO<sub>2</sub> and observed a performance similar\nto that of traditional powdered materials. Along with harmful gas\nadsorption, we also have evaluated the permeation and reactivity of\nthese MOF/textile composites toward chemical warfare agents (CWAs)\nlike GD (soman), HD (mustard gas), and VX. In combination, these results\ndemonstrate a fundamental advancement toward establishing a consistent\nstrategy for the hydrolysis of nerve agents in real-world scenarios.\nThis approach can substantially increase the protection toward CWAs\nand enhance the effectiveness of protective equipment such as fabrics\nfor protective garments. This dip-coating method for the integration\nof multiple MOFs on a single textile fiber unlocks a wealth of possibilities\nand paves the way for future innovations in the deployment of MOF-based\ncomposites.
