“…It is desirable in many application areas consist of broad range of markets including automotive, sporting goods, medical devices, and construction. In addition to these dominant fields, TPU can gain shape memory actuation property as it is filled with conductive carbonaceous fillers, [25][26][27][28] it can be used as a strain sensor because of it possess high flexibility, 29 it can behave as an actuator thanks to its electro-striction effect, [30][31][32] and it can gain photoluminescence, 33 ablative, 34 gas and moisture barrier 35,36 properties with the addition of fullerene. These characteristics give opportunity to material researchers for developing multifunctional composite materials having specific properties meet requirements of several applications in combination with performing various functions.…”

Thermoplastic polyurethane (TPU) composites filled with fullerene in the range from 0.5 wt% to 2 wt% were fabricated using melt-compounding. Fullerene addition levels up to nearly twofold increase in tensile strength, percent elongation, and modulus of TPU. The mechanical properties are improved as modified C 60 content decreases. Fullerene loadings also enhance thermal stability of TPU. Glass transition temperature decreases by the inclusion of C 60 into TPU matrix. Composites exhibited the improvement for storage modulus and vibration-damping behavior. The UL-94 rating and limiting oxygen index value of TPU are also extended to higher values after C 60 loadings. Adjuvant effect is observed on fire performance in which pristine C 60 inclusions and higher concentrations of C 60 exhibit better fire performance. Additions of C 60 give identical melt flow index values with that of TPU. Modified C 60 particles disperse more homogeneously than pristine ones into TPU matrix because of the improvement in interfacial interactions between fullerene and polyurethane elastomer.

“…Some special preparation methods, e.g., hydrogel, electrospinning, thermoset curing are suitable to develop SPN. In addition, it is worth to design SPN by readily available technology, for example, using coreshell templating [121][122][123], foaming [124], UV curing [125,126], 3D and 4D printing [127,128]. The addition of nanofiller could improve the performance of SMP and SHP nanocomposites attributed to their reinforcing-ability, nucleating-ability, and inherent functionalities (e.g., thermal conductivity, electrical conductivity).…”

The development of smart polymer nanocomposites (SPN) has been an area of high scientific and industrial interest in recent years, due to fantastic improvements achieved in these materials. SPN found potential applications in shape memory, self-healing, self-sensing, self-heating, self-cleaning, and energy harvesting. This mini-review highlights the current research and development on SPN, specifically on shape memory polymer (SMP) and self-healing polymer (SHP) nanocomposites. The processing techniques for SPN nanocomposites, for example, polymerization, melt-compounding, solution mixing, electrospinning, and thermoset-curing are discussed. Some of the potential strategies to modify the properties of SMP and SHP nanocomposites are highlighted. The future perspective and recommended works for the SPN nanocomposites are shared in this mini-review.
