Characterization of POSS-PCU scaffolds of varying surface porosities. (A) Scaffolds were analyzed for their maximum stress, percentage strain and Young's modulus, which showed minimal changes between scaffolds. (B) ATR-FTIR spectroscopy demonstrated no changes between scaffolds. (C) Surface wetness via captive bubble contact angle also remained unchanged. (D) Permeability testing revealed the most significant changes following dusting with sucrose, which increased flow rate through the scaffold. Experiments were performed in triplicate and analyzed using a Kruskal–Wallis test with Dunn's correction for multiple comparisons. Statistical significance is displayed as *p < 0.05, **p < 0.01.
