“…However, to date most of these polymers are only thermo‐sensitive, which cannot be precisely controlled and locally responsive, so they dissatisfy the growing practical requirements . Hence, it is expected to not only explore more channel stimuli‐responsive smart polymers, but also to design multifunctional materials including shape memory and self‐healing behaviors …”

Shape memory and self‐healing stimuli‐responsive polymeric materials have aroused extensive research interests due to their special functionality. In this work, a kind of novel and fast electric‐triggered self‐healing shape memory polymeric composite, based on polycaprolactone‐polylactic acid (PCLPLA) copolymer and reduced graphene oxide with embedded carbon nanotubes (CNTs@rGO), are prepared via a facile method. Interestingly, the CNTs@rGO‐PCLPLA composites show improved mechanical properties, excellent electrical conductivity, and could recover their original shape within 60 s by applying 1.42 V mm−1 electric field. Meanwhile, the proposed networks can be self‐heal rapidly and efficiently under electrothermal effect. These offer for the new material promising practical applications in aerospace, artificial skins, and electronic sensors.

“…Two prerequisites are considered for the material to recover from the mechanical deformation: switching transition between different phases should be reversible, supported by a stable polymer network responsible for a stable original shape. After mechanical deformation is stimulated, shape-memory polymers can fix the temporary structure via various transitions, such as liquid crystal anisotropic transition, molecule cross-linking, crystallization melting or supramolecular association/disassociation [ 1 , 90 ]. Normally, shape-memory polymers show recoverability from strains, but due to poor mechanical properties, less satisfying recovery from stresses is observed [ 3 ].…”

Intelligent materials, also known as smart materials, are capable of reacting to various external stimuli or environmental changes by rearranging their structure at a molecular level and adapting functionality accordingly. The initial concept of the intelligence of a material originated from the natural biological system, following the sensing–reacting–learning mechanism. The dynamic and adaptive nature, along with the immediate responsiveness, of the polymer- and fiber-based smart materials have increased their global demand in both academia and industry. In this manuscript, the most recent progress in smart materials with various features is reviewed with a focus on their applications in diverse fields. Moreover, their performance and working mechanisms, based on different physical, chemical and biological stimuli, such as temperature, electric and magnetic field, deformation, pH and enzymes, are summarized. Finally, the study is concluded by highlighting the existing challenges and future opportunities in the field of intelligent materials.

Polymer composites for structural applications are prone to damage emanating from cracks which are formed within the material, where detection is not easy and repairing almost not feasible. Material cracking results in mechanical deterioration of polymer composites for microelectronic components, which can result in electrical failure. Microcracking occurring as a result of thermally and mechanically induced fatigue is challenging for effective polymer performance. Self-healing composites are materials exhibiting capability of automatically recovering when damaged. They derive their inspiration through biological systems similar to the human skin, which exhibit a natural tendency to undergo healing by themselves. Stretchability is a factor enabling electronic devices to properly align to irregular 3-D structures, such as soft and movable parts. Stretchable electronics offers materials with the ability to conform to soft and nonplanar composites while enabling movement of biological tissues. Therefore, this article elucidates very recently emerging advancements on self-healing composites, stretchable composites, and sensors. Future market disposition and application of self-healing composites are also presented.
