Aerosol Jet Printing of the Ultramicroporous Calcium Squarate Metal-Organic Framework
CHEMISTRY OF MATERIALS(2022)
摘要
Efficient methods to deposit thin layers of metal- organic frameworks (MOFs) are needed to integrate these microporous materials into microelectronics, sensing devices, and membranes. Herein, we report for the first time the direct aerosol jet printing of a MOF material. The ultramicroporous MOF [Ca(C4O(4)) (H2O)] (UTSA-280) was deposited from an aqueous precursor solution. In addition to blanket coatings, aerosol jet printing provides direct access to patterned coatings with a resolution of 100 mu m via a digital, maskless approach. Moreover, by enabling spatial control over the layer thickness via the number of passes of the nozzle, this direct-write approach presents a more accessible alternative to advanced patterning techniques such as grayscale lithography.
