Multifunctional Shape‐Memory Polymers [PDF]
Advanced Materials, 2010 AbstractThe thermally‐induced shape‐memory effect (SME) is the capability of a material to change its shape in a predefined way in response to heat. In shape‐memory polymers (SMP) this shape change is the entropy‐driven recovery of a mechanical deformation, which was obtained before by application of external stress and was temporarily fixed by ...
