カーボンナノチューブ分散ポリマー複合材料のマルチスケールモデリングと力学・物理特性評価

Flexible pressure sensors are of broad interest for applications including human-machine interfaces, wearable electronics, and object/motion detection. However, complexities associated with constituent materials, fabrication processes, sensing mechanisms, and hardwiring often hinder the large-scale applications of using high performance pressure sensors reported in the literature. Here we demonstrate a large-area, highly flexible, conformable, and mechanically robust pressure sensor using a silicone elastomer with an embedded nonwoven textile carrier coated with carbon nanotubes. The selected silicone polymer allows through-thickness deformability of the sensor while the high modulus textile carrier ensures in-plane stiffness and stability. The sensor has an initial electrical conductivity of 4.4 ± 0.38 S/m and is fabricated using a straightforward dip coating and polymer infusion process and can be easily scaled-up for large-scale applications. On the basis of its hierarchical composite structure, this piezoresistive pressure sensor possesses extremely high resilience under compression, a repeatable monotonic positive pressure correlation, and an ultrawide elastic working range (5.5 ± 0.5 MPa) that can be segmentally linearized. A true two-dimensional modality for spatial pressure mapping is realized by utilizing electrical impedance tomography (EIT) and demonstrated to yield conductivity maps that can estimate the location, shape, and amplitude of both localized and distributed pressure with simple contact areas.

A distributed friction model for energy dissipation in carbon nanotube-based composites

: Nanotubes have been targeted for potential applications ranging from the next generation of computers and flat-panel displays to structural and functional materials. In addition to their well-known stiffness (> 1 TPa) and strength (-30 GPa) properties, carbon nanotubes also possess exceptionally high electrical and thermal conductivities, with the axial thermal conductivity near that of crystalline diamond. The unique mechanical and physical properties of nanotubes offer tremendous opportunity for the development of multijunctional composites. Under this research program an integrated effort to processing. characterization, and analysis/modeling of nanotube-based composites was undertaken. Through this research work a fundamental understanding of the processing/structure/property relations in carbon nanotube- reinforced composites has evolved. Ultimately, the establishment of these basic relationships will enable the nanoscale design of nanotube-reinforced materials for Air Force and aerospace systems.

Effect of nanotube waviness on the electrical conductivity of carbon nanotube-based composites

Despite tremendous efforts toward fabrication of three-dimensionalmacrostructures of two-dimensional (2D) materials, the existing approachesstill lack sufficient control over microscopic (morphology, porosity,pore size) and macroscopic (shape, size) properties of the resultingstructures. In this work, a facile fabrication method for the wet-chemicalassembly of carbon 2D nanomaterials into macroscopic networks of interconnected,hollow microtubes is introduced. As demonstrated for electrochemicallyexfoliated graphene, graphene oxide, and reduced graphene oxide, theapproach allows for the preparation of highly porous (> 99.9%)andlightweight (<2 mg cm–3) aeromaterials with tailoredporosity and pore size as well as tailorable shape and size. The uniquetubelike morphology with high aspect ratio enables ultralow-percolation-thresholdgraphene composites (0.03 S m–1, 0.05 vol%) whicheven outperform most of the carbon nanotube-based composites, as wellas highly conductive aeronetworks (8 S m–1, 4 mgcm–3). On top of that, long-term compression cyclingof the aeronetworks demonstrates remarkable mechanical stability over10 000 cycles, even though no chemical cross-linking is employed.The developed strategy could pave the way for fabrication of variousmacrostructures of 2D nanomaterials with defined shape, size, as wellas micro- and nanostructure, crucial for numerous applications suchas batteries, supercapacitors, and filters.
