Ultrahigh-throughput cross-flow filtration of solution-processed 2D materials enabled by porous ceramic membranes

Printed electronics is a disruptive technology in multiple applications including environmental and biological sensors, flexible displays, and wearable diagnostic devices. With superlative electronic, optical, mechanical, and chemical properties, two-dimensional (2D) materials are promising candidates for printable electronic inks. While liquid-phase exfoliation (LPE) methods can produce electronic-grade 2D materials, conventional batch separation processes typically rely on centrifugation, which requires significant time and effort to remove incompletely exfoliated bulk powders, hindering the scale-up of 2D ink manufacturing. While cross-flow filtration (CFF) has emerged as a promising continuous flow separation method for solution-processed 2D nanosheets, previously demonstrated polymer CFF membranes necessitate low 2D nanosheet concentrations to avoid fouling, which ultimately limits mass throughput. Here, we demonstrate a fully flow-based, exfoliation-to-ink system for electronic-gr..., , , # Ultrahigh-throughput cross-flow filtration of solution-processed 2D materials enabled by porous ceramic membranes [https://doi.org/10.5061/dryad.gmsbcc2xn](https://doi.org/10.5061/dryad.gmsbcc2xn) ## Description of the data and file structure Files are stored in Origin project (.opj) or Excel (.xls) format File Naming Each file contains the dataset relevant to the manuscript and/or supplementary information. Pressures and concentrations contains the permeate concentration of polymer and ceramic membranes for different transmembrane pressures and flow rates.
