摘要

Abstract

MXene is a novel 2D lamellar material with excellent hydrophilicity and permselectivity. MXene was introduced in the P84 polymer matrix and the matrix was crosslinked with triethylenetetramine (TETA) to improve the permselectivity and solvent resistance of the polyimide membrane. The membrane was characterized with SEM

AFM and ATR-FTIR

and effects of MXene content on the membrane morphology and separation performance are investigated. The membrane prepared with 18% P84 and 1% MXene shows high rejection (100%) to gentian violet (408) and high flux (268 L·m

) at 0.1 MPa and ambient temperature. MXene endows the membrane with much water channel and denser functional layer which improves the membrane performance obviously. The membrane shows excellent solvent resistance to dimethylformamide (DMF)

acetone and methanol after crosslinking with TETA during the 18 days of immersion.
