In order to solve the bottleneck problems including uniform distribution, and oxidation resistance of nano carbons in oxide ceramics, C/MgAl2O4 composite powders were prepared with MgC2O4·2H2O, MgO2, Al2O3, and Al as raw materials via combustion method under argon atmosphere. The maximum adding amount of MgC2O4·2H2O is 34.34 wt%. The phase compositions and microstructures of combustion products were characterized through X‐ray diffraction (XRD), scanning electron microscope (SEM)/EDX, and Raman spectroscopy. The results showed that the phases of products are mainly composed of MgAl2O4 and carbon. The prepared MgAl2O4 has granular and rod‐like morphologies, and the free carbon (1.172 wt%) exists between particles of MgAl2O4. Moreover, the addition of FeC2O4 as catalyst in raw materials ratio would be beneficial for improving crystallization of in situ carbon generated in the products. The oxidation activation energy of the prepared C/MgAl2O4 composite powders was calculated as 143.01 kJ/mol which was 22.17% higher than that of carbon black/MgAl2O4 powders (117.06 kJ/mol), suggesting that the C/MgAl2O4 composite powders prepared by combustion synthesis have excellent oxidation resistance.

“…The dimensional stability is consequently increased owing to the tightly crosslinked internal geometry which induces elevation of the storage modulus. [ 36 ] As the tightly crosslinked structures depress swelling of moisture, [ 37 ] the reduced moisture absorption of poststructures has a positive effect on long‐term dimensional stability as shown in Figure 2e. Typically, prestructures have significantly lower mechanical strength than poststructures.…”

The collective assembly of finite building blocks can induce complicated scaled‐up architecture for structural diversity and multifunctionality. In this study, the concept of 2D to 3D shape morphing via frontal photopolymerization is employed for the rapid and repetitive fabrication of geometrically tailorable building blocks. The photoabsorber generates an internal stress gradient which induces a mismatch of volumetric shrinkage within a photocured monolithic 3D structure. The final 3D curvilinear architecture is investigated through systematic analysis by controlling the spatiotemporal conditions of 3D shape morphing. The spatiotemporal effect consists of pre/postcuring methods and geometry of the 2D patterns inspired by fractal elements including even/odd condition, spirality, and self‐similarity. Finally, the concept of collective assembly is introduced to construct multiple objective architectures. Each morphed structure contributes to the assembly of hierarchical 3D structures as a building block. Inspired by famous architectures, the collective hierarchical 3D structures are demonstrated by replicating the form of certain landmarks. In addition, scaled‐up assembled 3D structure can withstand 150 times of its own weight and can be applied for the frame of electronic devices. The collective assembly of programmable building blocks has the potential for various versatile applications in rapid prototypes of optical metamaterials, antennas, and curved electronic devices.

“…Specifically, the storage modulus at 30 °C was significantly enhanced from 600 MPa for the pristine fabric composites to 1,115 MPa for the SiC@fabric composites. This dramatic increase in the storage modulus indicates that the interfacial interactions between the SiC@hybrid-fabric and resin matrix are strong enough to ensure an effective load transfer to the hybrid-fabric, resulting in high mechanical strengths [48,49]. Moreover, the WS 2 -AlN micro-filler reinforcements within the resin matrix serve as the network centers to dissipate the local stress evenly and restrict the movements of the polymer chains, allowing a further increase in the stiffness of the hybrid PTFE/glass fabric composites.…”

The high specific-strength of glass fibers and exceptional self-lubrication of polytetrafluoroethylene (PTFE) fibers promote the potential application of hybrid PTFE/glass fabric composites in the tribological field, but their weak interfacial adhesion and inferior thermal properties significantly inhibit their tribological performance and reliability. Herein, a hybrid of polydopamine/silicon carbide/polyethyleneimine (PDA/SiC/PEI) functional coating was co-deposited onto the hybrid PTFE/glass fabric surface through a one-step impregnation method, leading to increased surface roughness and abundant amine groups. Tensile and peeling tests showed that this functional coating offered 47.8% enhancement in the fabric/matrix interfacial adhesion without compromising the strength of the pristine fabric. Moreover, the additional incorporation of WS2, and aluminum nitride (AlN) micro-fillers contributed to the development of a high-quality tribofilm and improved the thermal properties of fabric composites. The results of wear tests proved that the hybrid-fabric composites, after the introduction of functional coating and micro-fillers, exhibited outstanding tribological performance, which was attributed to the superior interfacial adhesion as well as the synergistic enhancement effects between WS2 and AlN micro-fillers.
