Permeability of Porous Poly(3-hydroxybutyrate) Barriers of Single and Bilayer Type for Implant Applications

Figure 6

Water permeability of porous, dense (nonporous), and bilayer films casted from template emulsions with 10% (v/v) of water and 2.9% (w/v) of Li₂SO₄ in the emulsion template. The permeability was normalized against the film thickness. Error bars indicate min/max deviation (𝑛=2-3).
