The threat associated with chemical warfare agents (CWAs) motivates the development of new materials to provide enhanced protection a reduced burden. Metal-organic frame-works (MOFs) have recently been shown as highly effective catalysts for detoxifying CWAs, but challenges still remain integrating MOFs into functional filter media and/or protective garments.

Metal-organic frameworks (MOFs) chemically bound to polymeric microfibrous textiles show promising performance for many future applications. In particular, Zr-based UiO-66-family MOF-textiles have been shown catalytically degrade highly toxic chemical warfare agents (CWAs), where favorable MOF/polymer bonding and adhesion are attained by placing a nanoscale metal-oxide layer on the polymer fiber preceding MOF growth. To date, however, nucleation mechanism of MOFs different metal oxides how...
Highly tunable metal–organic framework (MOF) materials, including, for example, UiO-66-NH2, are known to be effective catalysts degrade chemical warfare agents (CWAs) with half-lives near 1 min. Therefore, many researchers have been actively working on producing supported MOF materials improve application effectiveness by using relatively slow solvothermal synthesis or repetitious stepwise layer-by-layer methods.

Rapid room-temperature synthesis of metal–organic frameworks (MOFs) is highly desired for industrial implementation and commercialization.

Biological muscles are composed of aligned actuatable fiber units to generate directional linear output, inspiring the design microstructures in artificial muscles. However, synthetic soft elastomers generally possess isotropic mechanical properties; therefore, a promising muscle (dielectric elastomer actuator) outputs nondirectional force or deformation. In this work, we report muscle-mimetic anisotropic dielectric with output driven by electric field. The millimeter-in-diameter fibers...
