Shape Memory Polymer NGP4510
Potting Type
Shape-memory polymers (SMPs), an emerging class of “smart materials” with dual-shape capability, are stimuli-responsive materials capable of returning from a programmed shape to their original shape upon exposure to an appropriate stimulus. Various types of stimuli-responsive SMPs, including thermal, light, pH, and moisture-responsive variants, have been applied in textiles to enhance or achieve smart functionalities. SMPs have also been extensively studied in the biomedical and aerospace industries.
