Abstract:: After being severely and quasiplastically deformed, upon applying a particular stimulus, some materials are able to recover their original shape. Such a phenomenon is known as the shape memory effect (SME) and materials with this feature are called shape memory material (SMM).Recent experiments reveal that heating/ chemoresponsive SMEs are almost intrinsic features of polymers. Further investigation confirms that based on various basic mechanisms, we are able to not only enable the SME in currently used materials, but also design a new SMM and further more optimize their performance. Hence, this technology may be termed advanced shape memory technology (ASMT), in order to distinguish it from the previous definition, which is limited to some particular SMMs. ASMT is able to reshape product design, fabrication and even recycling. This paper aims to review recent development in this area.
