Abstract (original English)

A general fabrication method for metal-organic framework (MOF) coatings through a vapor sublimation and deposition process is reported. The vapor-phase fabrication mechanism relies on the interplay between thermodynamic properties and the solid-vapor interface reaction. The processing parameters of ion concentration, vapor pressure, and system temperature enable control of the sublimation rate, and ion-linker nucleation and coordination reactions occur at the dynamic solid-vapor interface to form the proposed MOF coatings. The reaction rate is controllable and is proportional to the sublimation rate during the fabrication process. On the basis of the proposed fabrication mechanism, experiments are facilitated to obtain combinations of multiple metal cores and a variety of functionalized linkers for vapor deposition from solid solution sublimation. The fabrication process involves pore size control, crystalline orientation customization, and encapsulation of cargo to form composite coatings, and these processes are implemented during the same one coating fabrication process. The initiation and manipulation of the nucleation radius and thus the nucleation rate are easy to control and are related to the fabricated MOF coatings with tunable crystalline morphologies. Moreover, the MOF coating thickness is a time-dependent process that is proportional to the sublimation rate and depo
