Figure 4: Hydrogel film evaluation. (a) The macroscopic visualization results of hydrogel film; (b) Results of swelling ratio. The iota carrageenan-polyvinyl alcohol hydrogel films (1 cm × 2 cm) were weighed in advance and weighed again at the interval time during the immersion process; C. Results of gel fraction. The iota carrageenan-polyvinyl alcohol hydrogel films were weighed and passing through soaking and drying processes repeatedly. Each value represented the mean ± standard error of the mean. *P < 0.01 compared to the contro
