ABSTRACT

The shape memory polymer (SMP) materials have the ability to return from a deformed shape and recover their original shape once they are exposed to the suitable external stimulus. The SME in the thermally stimulated SMPs is totally motivated and pivoted on the glass transition temperature. The internal chemical structure is responsible for the SME mechanisms of SMP materials. Electro-responsive SMPs incorporating special conductive particles are capable of showing indirect activation by generating a Joule heating inside the material when subjected to electrical voltage. SMPs have emerged recently as a major competitor to the other types of shape memory materials (SMM) and rapidly grew in a varied range of applications, especially in the aerospace industry because of their lower density and high strain recoverability.
