“Tuning the trigger temperature is only one part of the story. We also engineered these materials to store large amount of elastic energy, enabling them to perform more mechanical work during their shape recovery,” said Chemical Engineering Professor Mitch Anthamatten who coordinated the research team of the University of Rochester. They envisaged medical sutures, artificial skin, body-heat assisted medical dispensers and self-fitting apparel as immediate possible applications. The researchers found the way to adjust the material’s stability and precisely set the melting point at which the shape change is triggered. In the case of a piece of the polymer the size of a shoelace, the team claims it would be able to lift a liter of soda. The findings are being published this week in the Journal of Polymer Science Part B: Polymer Physics.
