Objective

Today focuses on the first synthesis of Polymer and Polymer-clay films.

Description

From Dr. Matt Hartings' Notebook

  1. Polymer-Clay Films
    1. Add 7mL of water to 1g of 22,000MW polyvinyl alcohol and 0.11g of sodium montmorillonite in a glass vial
    2. Stir the solution with constant heating at 75C until the polymer is dissolved and the clay is dispersed (~15 minutes)
    3. Cool the solution to room temperature
    4. Add 0.5mL 0.8 wt% glutaraldehyde.
      1. NOTE: Perform step 4 in the hood
    5. Stir for an additional 3 minutes to ensure homogeneity
    6. Pour solution into a teflon dish to dry until the next class
  2. Polymer Films
    1. Add 7mL of water to 1g of 22,000MW polyvinyl alcohol in a glass vial
    2. Stir the solution with constant heating at 75C until the polymer is dissolved (~15 minutes)
    3. Cool the solution to room temperature
    4. Add 0.5mL 0.8 wt% glutaraldehyde.
      1. NOTE: Perform step 4 in the hood
    5. Stir for an additional 3 minutes to ensure homogeneity
    6. Pour solution into a teflon dish to dry until the next class
