Objective

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

Description of todays protocol taken from 08-27-14 link to prepared the starting materials from Matt Hartings Notebook

  1. Polymer-Clay Films
    1. Add 7mL of water to 1.0023g of 22,000MW polyvinyl alcohol and 0.1102g 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
  1. Polymer Films
    1. Add 7mL of water to 1.006g 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
