Comparison of equilibrium water uptake between thin films and scaffolds at 37°C.

Compositions of films and scaffold specimens	Equilibrium water uptake for thin films (g/g)	Equilibrium water uptake for scaffolds (g/g)
100/0 PHBV/PLLA	0.01	1.24
50/50 PHBV/PLLA	0.03	1.35
10% nHA in 50/50 PHBV/PLLA	0.09	2.97
