Previously, we 3D-printed polymer-zeolite monoliths by layer-wise phase separation. Importantly, this technique used liquid printing dopes, which exhibit a better rheology than traditional bentonite inks. In this work, we expanded polymer printing to metal−organic frameworks (MOFs) to address their rheological limitations. Initially, MOF-74 and HKUST-1 monoliths, with a composition of 40 wt % MOF and 60 wt % polyamide(imide) (Torlon), were printed. However, only HKUST-1 exhibited full crystalline retention. In contrast, the polymer solvents partially decomposed MOF-74, and the retained crystals were used as growth seeds. This approach produced dense MOF film monoliths with 40 wt % loading. The analysis of CO 2 adsorption capacities revealed CO 2 uptakes proportional to MOF loading for HKUST-1@Torlon monoliths. Moreover, secondary growth led to a 5-fold increase in CO 2 capacity for MOF-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
