Of all the materials produced commercially, the bulk of poorly performing materials are depicted as those, which cannot resist change in the face of environmental stimuli. Poor performance, leading to failure, has resulted in great replacement costs in most every field imaginable from construction materials to pharmaceutical preparations. Ironically, many materials are sought and employed because they change significantly and quickly in response to environmental stimuli. For instance, shape-recovering biomaterials describe one application. In this course, the thermo-kinetic aspects, production, uses & testing of quick-changing organic materials will be discussed.
