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 ...

Triple-shape memory effect in 3D-printed polymers
eXPRESS Polymer Letters, 2020 A triple-shape memory effect represents that polymers can memorize two temporary shapes and show a subsequent recovery from the second temporary shape to the first temporary shape and further to the permanent shape with heating, which provides more ...

Mechanical and Shape Memory Properties of Poly(vinyl acetate)/Poly(lactic acid) Blends [PDF]
علوم و تکنولوژی پلیمر, 2018 Hypothesis: Shape memory polymers (SMPs) are intelligent materials that can be set into temporary shape and return to their permanent (original) shape when an external stimulus is applied. Poly(vinyl acetate) (PVAc) is a low cost biopolymer. However, its
