  1. Shape Memory Polymers“Veriflex”(TM) by Corey M. Fitzgerald MEEN 3344

  2. Shape Memory Polymers • First introduced in Japan 1984, then U.S. • Special blend of two of more polymers • Ex. Polyethylene, Polyisoprene, and Polyurethane • Covalent cross-linked bonds • Uses shape-memory effect by thermal induction • Change of Shapes by thermal stimuli • Permanent, Temporary, and Permanent • Lightweight and high-energy diffusion • Cheap and efficient alternative to shape-memory alloys • Also pliable and can be stretched, bent, and folded

  3. “Veriflex” (TM) • Developed by Cornerstone Research Group (CRG) 2004 • Shape memory polymer resin • Thermal Activation customizable from -20F to 520F • High temperature elastic, and flexible state • Low temperature returns to rigid state and very strong • Reshaped several times without losing material integrity

  4. Potential Applications • Morphing wing structure • Self-repairing auto bodies • Custom reusable mandrels • Self-deployable structures for space • Medical devices (invasive surgery)

  5. Current Applications • Automatic chokes for combustion engines • Protection covers for assembly lines • Damping material • Spectacle frames • Utensils for handicapped people • artificial finger nails
