“…The 50% UiO-66/PVDF and 50 wt % UiO-66-NH 2 /PVDF MMMs showed higher ultimate tensile strengths (8.2 and 10.0, respectively) but less than 6% elongation at break (Figure and Table S2). The strength of the PVDF composites is on the order of PPE polymers used in nitrile or butyl protective gloves (22.7 and 9.1 MPa, respectively). , However, PPE gloves require high ductility, as shown by nitrile and butyl materials also having elongations at break over 550%. , …”

“…37,38 However, PPE gloves require high ductility, as shown by nitrile and butyl materials also having elongations at break over 550%. 37,38 Using the flexible PUU polymer yielded very ductile MOF composite materials. The 20 and 30 wt % UiO-66/PUU MMMs showed extremely high elongations and all tests resulted in elongations of break above 1500% or no break at all within the limits of the test (Figure 3 and Table S2).…”

Metal–organic framework (MOF)–polymer hybrid materials have been investigated for use in personal protective equipment (PPE) for combating chemical threats. However, few of these composite materials have demonstrated the desired processability or balance of strength and ductility suitable for modern textiles. In this work, a poly(urethane urea) (PUU) polymer was synthesized to mimic solution-processable spandex for MOF composites that have combined advantages for both the force the composite can withstand (strength) and the ability of the material to deform under strain (ductility). UiO-66/PUU mixed matrix membranes (MMMs) with up to 50 wt % UiO-66 MOF showed both high strength and ductility. UiO-66 and UiO-66-NH2 MMMs with PUU mechanically outperformed previously studied 50 wt % MOF/poly(vinylidene difluoride) (PVDF) MMMs. Testing of MMMs against the chemical warfare agent simulant dimethyl-4-nitrophenylphosphate (DMNP) revealed that the polymer plays an important role, with UiO-66-NH2/PUU MMM showing the fastest hydrolysis rate. Ductile fibers of 50 wt % UiO-66 and UiO-66-NH2 PUU composites were successfully prepared and showed remarkable handling properties and activity toward DMNP hydrolysis with 50 wt % UiO-66-NH2/PUU fibers performing better than any of the MMMs tested. These MOF–polymer composites could also be electrospun into nanofiber mats, which further illustrates the diverse range of processing techniques available for these materials.

“…As part of an overall characterization task (ref [1][2][3][4], the permeation properties and rates at room temperature were determined in air and hydrogen (3). In an effort to expand the data to temperatures other than room temperature, a North Butyl 30 mil glove was tested at room, 50, and 75°C.…”

“…The gloves from these vendors, with the composition and nominal thickness listed in Table 1 have been tested for permeability, tensile, Thermogravimetric, Dynamic Mechanical Analysis and now puncture resistance. The results of the other characterizations are reported separately (1)(2)(3)(4). A standard ASTM puncture test methodology (5) was used.…”
