Overview

Randomized trial demonstrates improved membrane selectivity in ultrathin films, suggesting new fabrication strategies.

Key Points

  • The aim is to explore a new thiol–ene photo-cross-linking strategy to create ultrathin selective membrane layers.
  • Introduced a thiol–ene interfacial photo-cross-linking process for ultrathin films.
  • Used vinyl-rich polymers and functionalized nanoparticles at a water/oil interface under UV light.
  • Examined factors like reaction time and dithiol type affecting film properties.
  • PDMS films showed thicknesses of 1–7 μm with near-zero water permeability.
  • PB films had reduced thickness of 60–200 nm and high selectivity (up to 2000) for phenol/NaCl.
  • Effective thiol–ene addition was confirmed through infrared spectroscopy and electron microscopy.
