Objective

Crosslink the films containing the quaternary ammonium salt.

Description

  1. Make 4 100 mL solutions of 94 mL water, 6 mL 12 M HCl
  2. Heat solutions up to 70 °C under the hood
  3. Add a film to each solution. Heat the films for 1 hr.
  4. Rinse the films with distilled water
  5. Make 4 solutions of 1.68 g sodium bicarbonate in 100 mL water.
  6. Place each film in a sodium bicarbonate solution.
  7. Soak the films in the sodium bicarbonate solution for 15 minutes.
  8. Rinse the films in distilled water and place under the hood to try.


Data

No Data Was Collected Today.


Notes

  • Half an hour after the films were placed into the HCl solution, the 8%, 1%, and 0.1% films shrank and the HCl solution was cloudy and had particulate floating around. After crosslinking was completed, aliquots were taken of all of the HCl solutions. UV-Vis spectra will be taken of the solution.
