Figure 1
SEM images of PHB film cross sections made with (a) no emulsion template, (b) 3%, (c) 6%, (d) 8%, (e) 9%, and (f) 10% of water in the emulsion template. The lithium salt content of the water phase was 2.9% (w/v) for all template emulsions. The scale bar is 2 μm and the magnification is ×5 k. The picture was taken with horizontal detection mode.
