Objectives

  1. Finish PVA/clay film preparation.
  2. Finish preparing DSC samples.
  3. Run DSC.
  4. Run X-ray on prepared microspheres with a 50:50 ratio of PVA/clay.
  5. Add deionized H2O to all prepared hydrogels in preparation for DSC.
  6. View prepared microspheres under microscope.


DSC

  • The general protocol for DSC was used
  • Specific DSC parameters and protocols set to analyze PVA/clay samples were:
   # Equilibrate sample at ~ -40°C
   # Ramp sample temperature up from 20-240°C
   # Ramp sample temperature down from 20-(-40°C)
   # Repeat segment #2 again
