Non‐Destructive Three‐Dimensional Imaging of Metal Organic Framework Mixed Matrix Membranes using Lab‐based X‐ray Computed Tomography

Abstract

Two‐dimensional composites of metal particles and polymers hold the promise to enable revolutionary applications. The research and development of these films have been ongoing for over 60 years and new manufacturing and characterization techniques keep increasing the pace of advancements. Retrieving quantitative information from these types of samples can be a difficult and time‐consuming task when using line of sight imaging modalities. In this work a mixed‐matrix membrane with Co‐containing ZIF‐67 was studied with lab‐based X‐ray computed tomography. The benefits and limitations of what the computed tomography technique has to offer are presented and discussed.
