“…Teflon-like polymer backbone) of nafion became the shell of composite nanofiber. More importantly, this experiment provides a simple route to fabricate organic-inorganic hybrid nanofiber, whereas its surface covered with uniformly organic polymer coating, such as combining shape memory polymer [35][36][37][38], novel active smart nanocomposite could be fabricated with shape memory polymer coated conductive inorganic materials.…”

“…Similarly, another major area of research into fiber-based SMPCs has been the use of carbon nanofibers in conjunction with boron nitride as a carbon nanopaper for Joule heating of SMP networks. In both cases, the researchers observed a faster shape recovery for an epoxy-amine system over an 80 sec heating period, reaching a maximal internal temperature of 87 C for carbon nanofiber-loaded epoxies and 185 C for carbon nanofiber/boron nitride composites [37,38]. Other fiber composites have seen uses in deployable satellites as the articulations for a solar panel skeleton in solarpowered satellites [39].…”

Shape memory polymers (SMPs) have been the focus of much research over the last few decades. From the novelty of temporarily fixing a threedimensional shape from a planar polymer sheet, to the uses that SMPs are seeing today as softening biomedical implants and self-deploying hinges, this class of smart materials has successfully been used to tackle a variety of biological, electrical, and mechanical problems. However, the properties of these networks are limited by the organic nature of the SMPs. To enhance their properties, researchers across the globe have looked into imparting the desirable properties of inorganic composite materials to these polymer networks. As the field of shape memory polymer composites began to grow, researchers quantified the unique enhancements that came at varying filler loading levels as a result of controlled material interface interactions. Specifically, the incorporation of nanofillers of various shapes and sizes leads to increased internal interfacial area relative to micro-and macrocomposites at identical loading fractions and imparts interesting mechanical, optical, electrical, thermal, and magnetic properties to these emerging nanocomposites. This new class of material, referred to in this review as shape memory polymer-inorganic nanocomposites (SMPINCs), allows a host of new interactions between the smart polymer and its surrounding environment as a result of the ability to control the internal environment of the polymer network and nanofiller. In this work, the reader is introduced to both the methods of preparing these composites and the effects the fillers have on the biological, electromagnetic, and mechanical properties of the resulting composite.

“…It was found that the electrical resistivity of the nanopaper enabled SMP nanocomposite is approximately 0.1 Ω·cm [44]. However, the interfaces between the nanopaper and SMP matrix could be a critical issue due to a large dissimilarity in their electrically and thermally conductive properties [37][38][39][40][41].…”

“…Utilization of electrically resistive heating to trigger the SME in the SMPs is desirable and convenient to apply in a number of practical applications, especially where directly thermal heating is not easily achieved [33][34][35][36][37].

Among these conductive ingredients, nanopaper, made from an aggregate of carbon nanotubes (nanofibers or graphene), has triggered enormous interest due to its superior electrical properties [41][42][43].…”
