Abstract Residual stress in polymers arises from the freezing of unstable molecular conformations. is critical because its relaxation can cause shrinkage, defects, and fractures polymer materials. The storage purposely enhanced to develop shape memory Unfortunately, mechanical still poorly controlled understood. An approach sense based on spectroscopic response carbon nanotubes explored. Raman exhibits a variable sensitivity strain when embedded that have experienced different thermal treatments. This unique feature opens up new possibilities for use as nanosensors.
