Shape-memory polymers vs. shape-memory alloys

Shape-memory polymers alter from appearance anamnesis alloys17 by their bottle alteration or melting alteration from a adamantine to a bendable appearance which is amenable for the shape-memory effect. In shape-memory alloys martensitic/austenitic transitions are amenable for the shape-memory effect. There are abundant advantages that accomplish SMPs added adorable than appearance anamnesis alloys. They accept a aerial accommodation for adaptable anamorphosis (up to 200% in best cases), abundant lower cost, lower density, a ample ambit of appliance temperatures which can be tailored, accessible processing, and abeyant biocompatibility and biodegradability.16
