“…High-performing polymers, such as polyimides, could also be used to produce tough actuator devices. As suggested by Ning et al [80], pre-dispersed SWCNTs could be used to produce highly aligned CNT matrices supported onto a polyimide film and used as a thermomechanical actuator. A multiresponsive actuator was described by Zhou et al [81].…”

In recent decades, micro and nanoscale technologies have become cutting-edge frontiers in material science and device developments. This worldwide trend has induced further improvements in actuator production with enhanced performance. A main role has been played by nanostructured carbon-based materials, i.e., carbon nanotubes and graphene, due to their intrinsic properties and easy functionalization. Moreover, the nanoscale decoration of these materials has led to the design of doped and decorated carbon-based devices effectively used as actuators incorporating metals and metal-based structures. This review provides an overview and discussion of the overall process for producing AC actuators using nanostructured, doped, and decorated carbon materials. It highlights the differences and common aspects that make carbon materials one of the most promising resources in the field of actuators.

“…Featuring excellent thermal stability, irradiation resistance and dielectric properties, polyimide (PI) has been pervasively used in the aerospace, aviation, and electronic fields [ 11 , 12 ]. PI/CNT nanocomposites, rather than pure PI matrix, show greater mechanical strength, Young’s modulus, electrical conductivity, and thermal stability [ 13 , 14 ]. However, the mechanical properties of the nanocomposites are still far behind the values predicted by the rule of mixtures.…”

To characterize the interfacial microstructure and interaction at a nanoscale has a significant meaning for the interface improvement of the nanocomposites. In this study, the interfacial microstructure and features of aligned multiwalled carbon nanotube (MWNT) and conjugated polymer polyimide (PI) with three molecular structures were investigated using small-angle X-ray scattering (SAXS), wide-angle X-ray diffraction (WAXD), and fluorescence emission spectroscopy. It was found that aligned MWNT/PI nanocomposites had a nonideal two-phase system with the interfaces belonging to long period stacking ordered structure. Attributed to the π–π stacking effect, MWNT/BTDA-MPD presented the most regular arrangement verified by fractal dimension. By adopting a one-dimension correlation function, each phase dimension in aligned MWNT/PI nanocomposites was calculated and verified by high resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD). The π–π stacking was demonstrated to be an important interaction between MWNT and PI via WAXD and fluorescence emission spectroscopy, and it was influenced by the linkage bond between benzene rings in PIs. This work is of significance to reveal the interfacial features between conjugated polymer and carbon nanotubes (CNTs), which is favorable for the interface design of CNT-based high performance nanocomposites.

“…The discovery of carbon nanotubes (CNTs) in the early 1990s revolutionized the materials science and opened a new perspective of research in nanostructured field. On the molecular level, CNTs have an outstanding combination of mechanical strength and stiffness, high aspect ratio, extraordinary electrical and thermal conductivities, and low density, making them ideal multifunctional materials that can be incorporated in FRPC . Several approaches have been reported to integrate CNT into traditional fiber/polymer composites: the dispersion of the nanoparticles into the polymer matrix and then the impregnation of the polymer/CNT mixture into the primary fiber assembly , the direct growth of CNT on reinforced fabrics substrate , spraying the nanotubes directly between layers of the prepreg , and the insertion of CNT films on the laminar interface of the FRPC .…”

In this work, multiwalled carbon nanotube buckypaper (MWCNT‐BP) was inserted at the middle‐plane of glass fiber/epoxy resin prepregs to obtain three‐phase nanostructured composite. Preliminary tests conducted by differential scanning calorimetry and thermogravimetric analyses (TGA) revealed that the proposed curing cycle to prepare the laminates in a hot compression‐molding machine was appropriated. The mechanical properties of the BP‐based composite studied by short beam shear and compression shear tests presented no improvements compared to the base laminate. On the other hand, the thermal properties of the nanostructured composite improved as demonstrated by dynamical mechanical analyses and TGA. Besides, the reflectivity results revealed an average value of −12.2 dB in the X‐band with a maximum attenuation of 99.4% of the incident wave at 9.5 GHz. The improvements in both thermal and electromagnetic properties demonstrate the potential for both structural and multifunctional applications of the obtained BP‐composite. POLYM. ENG.
