- Additional information
- The Polylactic acid (PLA) family is currently a subject of intensive study, arising from its environmentally benign origins in plant oil, biodegradability and bioresorbability in biomedical implant applications. They are semi-crystalline polymers, with the level of crystallinity varying between different PLAs and highly influential on mechanical and biodegradable capabilities. We use finite element modelling at a crystallite length scale to evaluate the effect of crystallinity on the forming and shape memory behaviour. Using experiments on shape recovery, a mathematical model of the amorphous matrix of a biomedical-like PLA grade is developed, to assist in design of biomedical shape memory devices.
