# | # Exfoliated Clays | ||
## An exfoliated clay has had all of its layers separated from one another. Instead of having layers in water, you have single sheets of material. This should change the absorption properties of the clay. We are going to test PVA-exfoliated clay materials against the regular PVA-clay material. | |||
## To exfoliate clay, you stir it in water for 24 hours. (Luckily Dr. Fox has done this for us already). | |||
## Stock solution 4% sodium montmorillonite | |||
### Determine how to make a film such that you make a 10% clay (1g of PVA, ?? of exfoliated clay solution). | |||
## Prepare a crosslinked film with the exfoliated clay in a similar manner to your other films | |||
# Powder Xray diffraction | |||
## We will discuss X-ray diffraction | |||
## You will dry and set up your samples for use in the xrd instrument. | |||
## I will show everyone how to use the instrument | |||
# Continue DSC analysis | |||
# Continue UVVis Analysis | |||
## We all need to have a discussion about what our possible sources of error are. | |||
## We may need to set up new malachite green/PVA-film experiment (just the PVA, not PVA clay at this point) | |||
