Room-temperature fabrication of superhydrophobic covalent organic framework (COF) decorated cotton fabric for high-flux water-in-oil emulsion separation

We report the preparation of a two-dimensional superhydrophobic covalent organic framework (COF)-coated cotton fabric via a rapid one-step method at room temperature. The COF-coated fabric was found to have stable superhydrophobicity and remarkable water-in-oil emulsion separation capacity with ultra-high flux under only gravity.

Automated summary

A two-dimensional superhydrophobic covalent organic framework (COF) was successfully coated onto cotton fabric via a rapid one-step method at room temperature. The COF-coated fabric exhibited stable superhydrophobicity and remarkable water-in-oil emulsion separation capacity with ultra-high flux under only gravity.
