Area of Science:

  • Materials Science
  • Chemical Engineering
  • Separation Science

Background:

  • Solvent resistant nanofiltration (SRNF) is crucial for separating organic solvent-based mixtures.
  • Polyimide (PI) membranes offer good chemical resistance but require optimization for specific separations.
  • Existing SRNF membrane preparation methods can be time-consuming and lack comprehensive parameter screening.

Purpose of the Study:

  • To optimize the performance of asymmetric, nanosized zeolite-filled PI SRNF membranes for rose bengal (RB) separation from 2-propanol (IPA).
  • To compare the efficacy of a combinatorial optimization strategy against a conventional screening approach.
  • To evaluate the developed membranes against commercial SRNF membranes.

Main Methods:

  • Preparation of PI-based SRNF membranes using the solidification of emulsified polymer solutions via phase inversion (SEPPI) method.
  • Optimization of nine synthesis parameters using a combinatorial strategy (genetic algorithm and self-adaptive evolutionary strategy) coupled with high-throughput experimentation.
  • Performance evaluation based on IPA permeance and RB rejection.

Main Results:

  • Combinatorially optimized SEPPI membranes achieved IPA permeances up to 3.3 L.m(-2) h(-1) bar(-1) and RB rejections around 98%.
  • These optimized membranes significantly outperformed membranes from systematic screening in terms of flux and selectivity.
  • The best SEPPI membranes exhibited higher IPA permeances than commercial SRNF membranes at comparable RB rejections.

Conclusions:

  • A combinatorial optimization strategy coupled with high-throughput techniques is highly effective for developing high-performance SRNF membranes.
  • The developed zeolite-filled PI SEPPI membranes show superior performance for RB/IPA separation compared to existing solutions.
  • This approach offers a pathway for rapid development and optimization of advanced membrane materials for challenging separations.
