Objective

  • Finish the film synthesis from Friday, August 29
  • Start a new film synthesis
  • DSC analysis of soaked films
  • FTIR analysis of soaked films

Protocol

  • Finish the film synthesis
  1. follow the protocol from Friday August 29th
  • Start new synthesis of Polymer and Polymer-clay films
  1. Using the synthesis method from Tuesday, August 26
  • DSC
  1. weigh pan and cap separately, record weight
  2. weigh out approximately 0.3mg of each film
  3. place then into a pan, and seal cap over each
    1. 10 samples total
      1. 4 polymer films that have been soaked in 2ppm, 8ppm, 80ppm, and 200ppm
      2. 4 polymer-clay films that have been soaked in 2ppm, 8ppm, 80ppm, and 200ppm
      3. 1 plane polymer film soaking in water, and 1 plane polymer-clay films soaking in water
  4. Input data information into the computer program (weights, position, reference)
  5. Place prepared capped trays into the machine and run analysis
