Objectives

  • Decant all microsphere samples prepared on 2013/03/20 and 2013/03/22
  • Rinse microsphere samples with hexanes and allow samples to completely dry.


Microsphere Work Up


Notes

  • A set of control microspheres will be prepared next time with only PVA MW:130,000 and PVA MW 146,000-186,000. These will be prepared on a 0.05g scale
  • A set control hydrogels will be prepared next time with only PVA MW 130,000 and PVA MW 146,000-186,000. These will be prepared on a 1g scale.
  • DSC will be run on all microsphere samples decanted and rinsed today.
  • X-ray diffraction will be run on all prepared microsphere samples in order to determine whether clay has agglomerated separately from the PVA. As a hydrophilic polymer, clay blends well and a peak shift below 10 degrees is a strong indicator of intercalation.
