Toughening and stabilizing MOF crystals via polymeric guest inclusion

Abstract

Improving the mechanical properties and stability of metal–organic frameworks (MOFs) is of significant interest due to their practical applications. Herein, we tune the mechanical properties of MOFs by filling the MOF pores with polymer chains. The mechanical properties reflect the filling rate, molecular weight, and inherent flexibility of the polymeric guests, imparting MOFs with improved resilience and toughness against mechanical pressures.
