Make PVOH hydrogels using isopropanol | |||
==Description== | ==Description== | ||
== | * 4 hydrogels were prepared. 2 were made using PVOH MW = 22,000, while the other two were made using PVOH MW = 146,000 - 186,000. For each molecular weight, one hydrogel was made with isopropanol alone, and one was made with isopropanol + glutaraldehyde. The amounts of isopropanol used is the same as in previous trials. | ||
# Measure out 2 samples of 1 g PVOH (MW = 22,000) and 2 samples of 1 g PVOH (MW = 146,000 - 186,000) | |||
# Dissolve in 20 mL water (Dissolve on heat) | |||
# Once dissolved, 0.0174 mL isopropanol was added to each sample. The samples were allowed to stir for a few minutes. | |||
# 1 mL glutaraldehyde was added to the 2 hydrogels that are isopropanol + glut | |||
# The hydrogels were placed in the freezer for 24 hours | |||
==Data== | |||
* No data was collected today. | |||
==Notes== | |||
* After an hour or so, the PVOH still had not dissolved, so the samples were transferred into larger beakers and an additional 10 mL water was added (total volume = 30 mL) | |||
