<u>Swelling</u> | |||
# One of the PVOH/glutaraldehyde films that had been crosslinked on 11/16 was removed from water. | |||
# The mass of the film was measured. | |||
# The film was dried in an oven set to 90°C for about 30 minutes and then was left to air dry for 1 week. | |||
<u>Porphyrin Film Preparation</u> | |||
* 3 porphyrin films were prepared. Two of the films contained the HCl seen in step 2. The HCl portion of step 2 was omitted. | |||
# 1 g of PVOH was dissolved in 7 mL H<sub>2</sub>O on a heated hot plate. | |||
# Once the PVOH dissolved, 1 mL of glutaraldehyde, 1 mL of porphyrin, and 2-3 drops of HCl was added. | |||
# The gel was stirred for 3 minutes and then was poured into a plastic dish and was allowed to evaporate for 1 week. | |||
