A new double-crosslinking method precisely tunes graphene oxide (GO) spacing in membranes. This enhances performance for isopropanol dehydration via pervaporation, advancing molecule sieving applications.

Area of Science:

  • Materials Science
  • Chemical Engineering
  • Nanotechnology

Background:

  • Graphene oxide (GO) shows promise for molecule sieving but suffers from poor separation performance due to difficulties in microstructure control.
  • Existing GO-based membranes often have limitations in precisely tuning their interlayer spacing for optimal separation.

Purpose of the Study:

  • To develop a novel double-crosslinking strategy for effectively tuning the interlayer spacing of graphene oxide (GO).
  • To fabricate and evaluate the performance of GO-based hybrid membranes for pervaporation (PV) dehydration of isopropanol.

Main Methods:

  • A double-crosslinking strategy was employed to modify the microstructure of graphene oxide.
  • Hybrid membranes were fabricated using this strategy and characterized using FTIR, XPS, water contact angle, and SEM.

  • Pervaporation dehydration of isopropanol was conducted to assess membrane performance, investigating effects of operating cycles, chitosan, and GO concentrations.

    • Main Results:

    • The double-crosslinking strategy successfully adjusted the interlayer spacing of GO within the hybrid membranes.
    • A hybrid membrane with 0.1 wt% GO demonstrated exceptional performance, achieving a flux of 4391 g/m²h and a separation factor of 1491.
    • Systematic investigation confirmed the influence of operating parameters on membrane performance.

    Conclusions:

    • The developed double-crosslinking strategy offers effective control over GO microstructure for enhanced membrane separation.
    • The high-performance hybrid membrane indicates significant potential for GO-based materials in pervaporation and other membrane separation technologies.
