Swelling behavior of PHB films with different PAA nanogel content. (a) % mass increase in PBS buffer, (b) % mass increase in Milli-Q water, (c) % thickness increase in PBS buffer, and (d) % thickness increase in Milli-Q water. ◊=PHB, □=PHB+5%PAA, Δ=PHB+10%PAA, X=PHB+15%PAA, ○=PHB+25%PAA. Error bars indicate one standard deviation (𝑛=3).
