Fig. 1

Composite foams containing (a) 0%, (b) 2.5%, (c) 5%, and (d) 10% gelatin. Images were taken using an optical microscope. a has pores of estimated pore sizes of 400 μm with thin walls. b has two pore sizes of 250 μm and 600 μm with walls thicker than that of the 0% gelatin. c and d have very large pores estimated to be 1500 μm along with pores in the walls measuring roughly 100 μm
