Procedures

Make Exchanged Clay Films

  • THP Bromide Exchanged Clay:
    • Add 7mL of water to ~1.0 g PVA and ~0.11 g of THPB exchanged NaMT in a glass vial
    • Stir the solution with constant heating at 75C until the polymer is dissolved and the clay is dispersed (~15 minutes)
    • Cool the solution to room temperature
    • Add 0.5mL 0.8 wt% glutaraldehyde.
    • Stir for an additional 3 minutes to ensure homogeneity
    • Pour solution into a teflon dish to dry until the next class
  • Choline Chloride Exchanged Clay:
    • Add 7mL of water to ~1.0 g PVA and ~0.11 g of CC exchanged NaMT in a glass vial
    • See above
