        • Due to their synthetic design, protein polymers are capable of combining the biological functionality of natural proteins with the chemical functionality and exceptional physical properties of synthetic polymers

    • Amorphous metals
      • No long range order
      • No grain boundaries
      • Less formation of slip plane when be applied a stress

      • Ferromagnetic martensite
      • Different variants can be aligned with the magnetic field to obtain quick and large shape changes
  • 15. Amorphous metal alloys
    • Amorphous alloy
    • It used to solidify the metal melt by ultra high cooling rate to obtain a thin band with a thickness of 0.01 to 0.1 mm. When the cooling rate is larger than 10 6 K/s, the metal band will have a non-crystalline structure which is named “amorphous” or “metallic glass”.
