Abstract Scope |
Metal-organic frameworks (MOFs) are a diverse class of materials that have proven useful for a wide range of applications including catalysis, gas storage, and absorption. Typical processing steps for MOFs are pelletization and extrusion. Thus, the mechanical behaviors of these materials are an important consideration but are rather unexplored. Here we consider the mechanical behaviors of the zirconium-based MOF NU-1000. Single crystal MOF particles were compressed in situ, and the experimental load-displacement response was used in conjunction with finite element modeling to determine the effects of phase purity and pore reinforcement on the measured elastic modulus and yield stress. The particles with an impurity phase displayed elastic moduli and yield stresses nearly an order of magnitude lower than their phase-pure counterparts. In contrast, the pore reinforcement showed no clear effect on the elastic modulus but increased the failure load by greater than 50%. |
