Figure 2.
Micrographs of PEUU/collagen scaffolds generated by varying the quenching temperature. (a, b) −20°C, (c, d) 0°C. For polymer notation refer to Table 1. Scaffold surface morphologies are seen in (a) and (c). Cross section morphologies are seen in (b) and (d). All scaffolds were prepared from 10% PEUU solution and a PEUU/collagen ratio of 80:20. Micrographs of scaffolds made at a quenching temperature of −80°C with the same PEUU solution percent and PEUU/collagen ratio are found in Figure 1e and f.
