Objective
Starting of synthesis for both polymer and polymer-clay films.
Description
Perform the following procedures (1 and 2) in parallel for the start to the synthesis of cross-linked polymer and cross-linked polymer-clay films.
Description of todays protocol taken from 08-27-14
link to prepared the starting materials from Matt Hartings Notebook
- Polymer-Clay Films
- Add 7mL of water to 1.0023g of 22,000MW polyvinyl alcohol and 0.1102g 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 1.006g 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
- The samples began to boil and water volume was lost to evaporation
- The mixtures were stirred for approximately 1 minute before being left out to dry.
