Objective
First synthesis of Polymer and Polymer + Clay films.
Protocol
From Dr. Hartings' Notes
- Polymer-Clay Films
- Add 7mL of water to 1g of 22,000MW polyvinyl alcohol and 0.11g of sodium montmorillonite 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.
- NOTE: Perform step 4 in the hood
- Stir for an additional 3 minutes to ensure homogeneity
- Pour solution into a teflon dish to dry until the next class
- Polymer Films
- Add 7mL of water to 1g of 22,000MW polyvinyl alcohol in a glass vial
- Stir the solution with constant heating at 75C until the polymer is dissolved (~15 minutes)
- Cool the solution to room temperature
- Add 0.5mL 0.8 wt% glutaraldehyde.
- NOTE: Perform step 4 in the hood
- Stir for an additional 3 minutes to ensure homogeneity
- Pour solution into a teflon dish to dry until the next class
Notes
Actual amounts of reactants
- 1.0024 g PVOH for polymer film
- 1.0010 g PVOH + 0.1103 clay for polymer clay + film
- After 10 minutes of heating at 75 degrees Celsius the temperature was raised to 120 to facilitate dissolving.
