The thermally induced shape-memory effect in polymers refers to the ability of certain polymer materials to "remember" a particular shape and return to that shape when subjected to a specific thermal stimulus. This phenomenon is a result of the unique molecular structure of shape-memory polymers (SMPs), which allows them to undergo significant reversible deformation upon heating and cooling. ### Key Concepts: 1. **Shape Memory Mechanism**: - Shape-memory polymers have two distinct states: a temporary shape and a permanent shape.
