Wettability and swelling degree of PEG/GBM composite hydrogels. (A) Water contact angle of hydrated composite films. Five technical replicates and two independent experiments: one-way ANOVA and Tukey’s multiple comparisons test; no statistically significant differences found. (B) Swelling degree of pre-dried hydrogels at different timepoints (5, 10, 20, 30 min, 1, 2, 3, 4 and 48 h). Five technical replicates and two independent experiments: one-way ANOVA and Tukey’s multiple comparisons test; * p < 0.05 vs. neat PEG hydrogels.
