- Time to attempt making more beads
- We're ditching yesterdays attempts and going to try expand on Eleni's group. They were able to create ribbons of PVA-Clay however we would like to form beads. Here is their procedure notes.
- A column was set up with Glutaraldehyde and hexane. Air is being bubbled through the column so in the attempt to mix the two
- PVA-Clay will be dropped down the column
- the PVA-Clay formed beads within the hexane and floated down the column. They did not crosslink fast enough if at all and they dissolved into the Glutaraldehyde.
- We needed a solvent that would still form beads with the PVA-Clay while being miscible in water. The PVA-Clay however was not forming beads within the solute but rather clumps.
- We attempted to add acetone to Glutaraldehyde and then add hexane to get rid of the solvent layers. The solution was not hydrophobic enough to form beads however. When only a slight layer of hexane and stirring were applied, it yielded no good results.
- We have decided to abandon the beads and begin synthesis of ribbons
- We filled a column with acetone and 1.5mL of Glutaraldehyde
- we then dropped in the PVA-Clay
