Area of Science:

  • Materials Science
  • Chemical Engineering
  • Environmental Science

Background:

  • Controlling interfacial polymerization is crucial for nanofiltration (NF) membrane fabrication.
  • Existing methods often require complex modifications to standard procedures.

Purpose of the Study:

  • To develop a simple method for controlling interfacial polymerization in NF membrane fabrication.

  • Examined diffusion kinetics of fluorescence-labeled piperazine (FITC-PIP).
  • Analyzed acyl chloride spreading behavior and polyamide layer formation using in situ Fourier transform infrared (FT-IR) spectroscopy.

Main Results:

  • The PEI/TA interlayer significantly reduced FITC-PIP diffusion kinetics.
  • Interfacial polymerization was effectively controlled, leading to improved polyamide layer formation.
  • The modified NF membrane achieved a water flux of 65 L m⁻² h⁻¹ at 0.6 MPa and >99% Na₂SO₄ rejection.

Conclusions:

  • The PEI/TA interlayer offers a facile strategy to precisely control interfacial polymerization for high-performance NF membranes.
  • This approach enhances membrane performance metrics, including water flux and selectivity.
  • The method demonstrates excellent long-term structural stability, suitable for practical applications.
