Double-Crosslinked GO Interlayer Framework as a Pervaporation Hybrid Membrane with High Performance.

ABSTRACT: Graphene oxide (GO), as a two-dimensional structure material, has attracted widespread attention in the field of molecule sieving. However, GO-based membranes usually exhibit undesirable separation performance because the microstructure of GO is difficult to adjust. Herein, a novel double-crosslinking strategy for tuning the interlayer spacing of GO is reported. The hybrid membrane fabricated by the double-crosslinking strategy was used for pervaporation (PV) dehydration of isopropanol. To achieve high-performance of the PV hybrid membranes, the effects of operating cycles, chitosan concentration, and GO concentration were systematically investigated. The PV hybrid membranes were characterized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, water contact angle
