Swelling kinetics of xerogels. The samples used for this study were H.6.20 (6% HOP and 20% of gelatin), L.6.20 (6% LOP and 20% of gelatin), N.6.20 (6% NOP and 20% of gelatin), and 0.20 solely gelatin (20% gelatin). The weight of N.6.20 at 72 h was not obtained due to the fragmentation of the hydrogel.
