Continuation of Film Synthesis

  • Following the protocol provided by Dr. Hartings, the films from last Friday, August 27, 2014, were transferred from the teflon dishes into a 250 mL beaker containing 0.2 M Sodium Sulfate solution with added sulfuric acid at 80°C.
  • After an hour of gentle stirring (2:00PM), the films were transferred to a warmed, 1% HCl solution at 80°C.
  • The PVA only film was torn into pieces by the stir bar during stirring while the PVA + clay film remained intact.
  • At 2:35PM, the films were transferred to a room temperature, 0.2M Sodium Bicarbonate solution for 15 minutes. As mentioned, this process will neutralize the acid present on the films.
  • Once the 15 minute neutralization was completed, the films were stored into separate beakers containing distilled water for the meantime.

Batch 2 Film Synthesis

  • 0.1144 g of Sodium Cloisite (Southern Clay Products) was added to 1.0068 g of PVA (MP Biomedicals)
