Polymer-Ti 3 C 2 T x composite membranes to overcome the trade-off in solvent resistant nanofiltration for alcohol-based system
Abstract(#br)Solvent resistant nanofiltration (SRNF) technology is an energy efficient and environmentally friendly alternative to purify alcohol-based mixtures, but there exists a challenge in overcoming the trade-off between membrane flux and rejection. Herein, as the representative of the emerging family of MXenes, Ti 3 C 2 T x nanosheets with abundant –OH groups are chosen as nanofillers to prepare SRNF composite membrane after being incorporated into two typical polymer matrixes: hydrophilic polyethyleneimine (PEI) and hydrophobic polydimethylsiloxane (PDMS).
