Fixant for cross linking of the films on Monday   2. Make film
with no glutaraldehyde (control)   3. Make film with
glutaraldehyde no isopropyl alcohol (control)   4. Make five
films varying in concentration of isopropyl alcohol, determine
amount of alcohol by calculating amount of OH groups on PVA   5.
Let all seven films dry over the weekend   Films and components
All films were heated on a hot plate until the PVOH dissolved in
the water. For films 5,6, and 7, additional water was added to
the gel to assist in the dissolution. Once dissolved, the film
was removed from heat and isopropyl and glutaraldehyde were
added. The isopropyl was added first and stirred for roughly 2
to 3 minutes. Glutaraldehyde was added last.    1. 0.5043 g PVOH
+ 6 mL water (this was the only small film prepared)   2. 0.5027
