Objective

  1. Time to make some beads!
    • Over the next few weeks we plan to refine this process and discover the most efficient synthesis of these beads.

Description

  1. Begin the Synthesis
    1. Measure out 0.0550g of Clay and 0.5000g PVA and place in a scintillating vial
  2. Dissolve the Solid
    1. Figuring out how much 1M HCl is necessary to completely dissolve the PVA and Clay
      • we want the minimum amount of acid but still dissolve in a timely fashion
      • we determined that we need at least 6mL of HCl and heat
  3. attempt at beads
    1. using a Pasteur pipette, drop the PVA-clay into solution


Data

Solution Number

  1. 0.0550g Clay + 0.5000g PVA
  2. 0.0554g Clay + 0.4989g PVA

Acetone Trial

  • PVA-Clay was not strong enough to hold a sphere but rather made string/fibers. This can be weaved into a sort of bead but this cannot be measured

Hexane Trial #1

  • HCl is immiscible in Hexane, spherical constitution of beads was overall maintained. Upon adding to Glutaraldehyde, the beads did not stay together.
  • Used 250μL Gluteraldehyde in 10mL Hexane
Initial creation of beads in Hexane.
Initial creation of beads in Hexane.

Hexane Trial #2

  • This time the Glutaraldehyde was rapidly stirred and the PVA-Clay solution was slowly dropped in. Bead formation was observed while stirring, however the beads were not given enough time to finish cross linking and stuck together.
  • Used 100μL Glutaraldehyde in 10mL Hexane

Hexane Trial #3

  • Bigger container and more time in between drops in order to allow more time to cross linking.
  • 200μL Glutaraldehyde in 150mL Hexane

Hexane Trial #4

  • Using a blender this time in attempt to make an emulsion.

Notes

This area is for any observations or conclusions that you would like to note.


Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
