Webb(a) Thermo responsive shape memory polymers: The shape memory polymers which change in shape with the change of temperature are called thermo responsive shape memory polymers. By far these are the most common shape memory polymers. (b) Electrical heating induced shape memory effect: The shape memory polymers are … Webb8 jan. 2016 · Among various shape-changing materials, the elastic nature of shape memory polymers allows fixation of temporary shapes that can recover on demand, whereas polymers with exchangeable bonds can undergo permanent shape change via plasticity. We integrate the elasticity and plasticity into a single polymer network. did aristotle believe the earth was round
