* In regards to the spectra, all samples maintained a quick diffusion rate indicating that dye crosslinking during the freeze / thaw cycle is pertinent when making hydrogels because it slows down the diffusion rate | |||
* For the hydrogels in which the dye was added, but not crosslinked into the material, their diffusion rate was the quickest -- a significant amount of dye leaked out of those hydrogels throughout the 2 hour period | |||
* Comparing the 50:50 vs. the 90:10 ratio of PVOH / clay, the hydrogels with 50:50 ratio had more dye leak out than the 90:10 ratio hydrogels indicating a more effective pressure stimuli | |||
