This figure by Penhasi and colleagues shows a new blend of a high modulus thermoplastic segmented polyurethane (PU) and poly(L‐lactide) (PLA) that was found to be immiscible but highly compatible such that the dispersed phase spontaneously organized into microspheres embedded in the continuous phase. A 80:20 w/w ratio of PU:PLA shows PLA microspheres in PU in a SEM image at ×500 magnification using a secondary electron detector (top), and TLM photograph after stretching at ×1000 magnification using a dark field technique (bottom). These systems may be used for structural implantable drug delivery systems. DOI: 10.1002/app.49517
