Metal-organic frameworks (MOFs) are promising materials for shock energy dissipation via nanopore collapse and powder compaction. In this work, we measured shock wave energy attenuation by ZIF-8 (a MOF with a zinc-2-methylimidazolate framework) using a tabletop laser-driven flyer-plate apparatus. Aluminum flyer plates 75-um thick were accelerated to speeds up to 2.0 km/s to impact the ZIF-8 film. The pressure of the shock waves that break out from ZIF-8 was measured by photon Doppler velocimetry (PDV). By comparing the shock profile with and without ZIF-8, we deduced the shock pressure attenuated by the ZIF-8 layer. We identified the two-wave structure of shocks in ZIF-8 caused by nanopore collapse. Electron micrographs of recovered shocked ZIF-8 show distinct zones in the shocked material corresponding to shock powder compaction, nanopore collapse and chemical bond destruction.
