Objective

Continued the synthesis of polymer and polymer-clay films. Begin the preparation of ionic liquid modified clays.

Description

  1. Completing the Synthesis
    1. the procedure for completing the synthesis of films may be viewed here.
  2. preparation of ionic liquid modified clays
    1. We are going to exchange the sodium in the sodium montmorillonite for an organic cation. The procedures are taken from these two sources (1, 2 along with Karlena Brown's thesis. We are working from the starting point that there are 92 miliequivalents (meq) of Na+ per 100g of montmorillonite.
    2. Add 1.1g of Sodium Montmorillonite (NaMT) to a scintillation vial containing 20mL of 50:50 HPLC grade water:ethanol.
    3. Determine the amount of cation to add if using either tributylhexadecylphosphonium bromide] to exchange 100% of the Na from the clay.
    4. Add this amount of phosphonium ion to the clay solution.
    5. Cap the vial
    6. Stir for 1 week.
    7. Vacuum filter using 0.2uM nylon filter paper
    8. Dry in oven at 90C overnight
    9. Grind with a mortar and pestle.
    10. Store in a dessicator
