The image shows how Soybean Polyurethanes (PUs) stand out for exhibiting excellent resistance to hydrolysis, good biocompatibility, and macromolecular design flexibility. Soy polyurethanes have separate phase morphology. The SEM micrographs created by Otávio Bianchi and colleagues show that the materials' topology is similar and little depends on the type of chain extender. However, the density of hydrogen bonds and the molecular relaxation of soy‐based polyurethane have a direct relationship with the structure of the chain extender. DOI: 10.1002/app.50709
