“…Composites reinforced with CNTs in low-density metals, such as aluminum and magnesium, have been actively developed and studied in the last decade [ 1 , 2 ]. In addition, a low-density metal foam coated by graphene was developed to sustain the low density and high strength [ 3 ]. Recently developed CNT-reinforced carbon matrix (CNT-C) composites have also shown great potential as lightweight, strong, and highly conductive materials [ 4 , 5 ].…”

By using the advantages of carbon nanotubes (CNTs), such as their excellent mechanical properties and low density, CNT-reinforced metal matrix composites (MMCs) are expected to overcome the limitations of conventional metal materials, i.e., their high density and low ductility. To understand the behavior of composite materials, it is necessary to observe the behavior at the molecular level and to understand the effect of various factors, such as the radius and content of CNTs. Therefore, in this study, the effect of the CNT radius and content on the mechanical properties of CNT-Al composites was observed using a series of molecular dynamics simulations, particularly focusing on MMCs with a high CNT content and large CNT diameter. The mechanical properties, such as the strength and stiffness, were increased with an increasing CNT radius. As the CNT content increased, the strength and stiffness increased; however, the fracture strain was not affected. The behavior of double-walled carbon nanotubes (DWNTs) and single-walled carbon nanotubes (SWNTs) was compared through the decomposition of the stress–strain curve and observations of the atomic stress field. The fracture strain increased significantly for SWNT-Al as the tensile force was applied in the axial direction of the armchair CNTs. In the case of DWNTs, an early failure was initiated at the inner CNTs. In addition, the change in the elastic modulus according to the CNT content was predicted using the modified rule of mixture. This study is expected to be useful for the design and development of high-performance MMCs reinforced by CNTs.

“…Namely, incorporating nanofillers into a polymer matrix can enhance damping performance. [270][271][272] However, the daunting agglomeration issue of nanofillers hinders the further improvement of damping property. [273][274][275][276][277] Toward this end, our group has prepared various nanoparticle ionic materials (NIMs) as novel nanofiller phases to enhance the damping property of polymer-based composites, such as including carbon nanotubes (CNTs)-based NIMs, graphene oxide (GO) based NIMs, (Reproduced with permission.…”

Porous liquids (PLs), an emerging type of flowing liquid materials that combine the merits of porous solids and flowing liquids, have garnered immense attention since the concept of PLs was proposed in 2007. Meanwhile, PLs have witnessed growing success in versatile synthesis strategies and emerging applications, especially since 2017. Given the lack of a timely comprehensive review, developing a prompt summary with a comprehensive understanding is undoubtedly urgent. Thus, this critical review offers a comprehensive summary of the progress in fundamental chemistry, developmental history, synthetic strategies, and emerging applications of PLs. First, the fundamental chemistry and developmental history are reviewed. Then, the synthesis strategies of PLs are highlighted. Additionally, crosscutting studies of pure theoretical simulations are reviewed. Meanwhile, the daunting characterization issues of PLs are analyzed. Next, the state-of-the-art of PLs applications is reviewed in detail. In the end, perspectives regarding the remaining challenges and future directions for PLs are presented. It is speculated that this critical comprehensive review of PLs could inspire scientific communities who focus on the taskspecific materials for various applications, such as gas sorption, membrane separation, catalytic conversion, chiral separation, thermal management and electrolyte, and so on.

“…Moreover, the storage modulus and loss modulus of L-SiC NN remain nearly identical in 100 000 compression-recovery cycles at 50 Hz and an oscillatory ɛ of ±2% (Figure 2I), indicating the superior mechanical and structural stability. 3,8,[21][22][23][24][25][26][27] The unique combination of high storage modulus and small damping ratio renders L-SiC NN different from existing viscoelastic materials, endows the L-SiC NN with promising potential for mechanical energy storage (Figure 2J).…”

Light, strong, and elastic ceramics are of great interest for widespread engineering applications but it is always been a challenge to design and fabricate such materials for the conflict that lightweight structure usually requires high porosity while high porosity often leads to low strength. Here, we report a lightweight (90.9% porosity) and ultra-strong SiC nanowires network (SiC NN) constructed by highly inter-bonded nanowires in a layered distribution through a facile way.The resulting lamellar SiC NN (L-SiC NN) exhibits a nearly complete compressive resilience from 20% strain while showing significantly high compressive stress (5.7 MPa). In particular, the L-SiC NN shows high storage modulus (12.3 MPa), small damping ratio (0.046), frequency invariant from 20 to 100 Hz, and fatigue resistance up to 100 000 compression-release cycles. In addition, the L-SiC NN possesses high-temperature stability up to 1100 • C in air and low thermal conductivity of 0.121 W m -1 k -1 . These integrated features make the L-SiC NN an attractive substitute for thermal insulators and mechanical energy storage in a harsh environment.
