OBJECTIVES

  • Begin X-ray analysis of microsphere samples
  • Begin to run DSC sample analysis on hydrogel samples previously prepared on 2/04/13
  • Continue making films containing both clay and PVOH variations to run X-ray analysis
  • Add H2O to hydrogel samples containing Rhodamine 6G dye in order to run DSC and X-ray analysis (leach out dye before analyses)

DSC Analysis: Mixed Hydrogels

DSC preparation and protocol involving instrumentation and usage can be found on 9/17/12 entry.

Sample Name Sample Mass (mg) Pan / Lid Mass (mg)
90:10 PVOH 146K 50% CEC NaMT w/ Bu3HdP+3.1049.78
90:10 PVOH 146K NaMT3.0149.99
  • Specific DSC parameters and protocols set to analyze dry clay samples included the following:
   # 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

Notes

  • In regards to microsphere preparations, in order to vortex the new microsphere samples being prepared more efficiently, a more advanced, efficient, and high speed vortexer will be used instead of a sonicator for vortexing samples.
  • X-ray analysis on 4/12/13 was solely run on the microsphere sample: 50:50 PVOH 130K 110% CEC Laponite w/ DMHXLBR
