Summary: This investigation demonstrates a method of preparing AM composites with hybrid reinforcements of short carbon fibers and Ni-MOFs. The porous MOFs provide the fibers with a large surface area, and the growth process is non-destructive and scalable. The study also shows the possibility of using Ni-based MOFs as a catalyst for growing MWCNTs on carbon fibers.

Summary: Multifunctional and easily-controlled self-healing rubbers with high performance were developed in this study. The composites showed satisfactory mechanical strength, photothermal conversion, and accurate self-healing. The self-healing capacity was realized through the construction of an ionic supramolecular network, and the photothermal effect of carbon nanotubes effectively promoted the healing process. These high-performance self-healing rubbers have great potential in various applications.

Summary: This study investigated the collaborative effect of different nanofillers in the carbon foam matrix. The results showed that the incorporation of nanofillers can enhance the microstructure, pore size, and uniform dispersion of samples. Among the different reinforcement materials, functionalized nanodiamonds were found to be more effective in improving the properties of carbon foam nanocomposites. Samples with 2 and 4 wt% CF/MWCNTs-FNDs exhibited the best thermal, mechanical, and electrical properties.

Summary: This paper presents a method for preparing conductive silicone rubber composites with low conductive percolation threshold and excellent piezoresistivity. By using high-pressure microfluidization technology, aqueous dispersions of carbon nanotubes and graphene were prepared and combined with cellulose nanofiber to create vertically aligned carbon nanotubes/graphene network foams. Liquid silicone rubber was then filled to obtain the composites, and the interface interaction was improved with a specific grafted copolymer. The resulting composites exhibited high electrical conductivity and compressive strength, and were used as a stable piezoresistor for detecting pedestrian steps when encapsulated in an insole.

Summary: This study investigates the effect of acid functionalized carbon nanotubes (FCNTs) on the microstructural development, thermo-mechanical, and gas barrier properties of epoxidized natural rubber (ENR 25) composites. It is found that the addition of 1% and 2% FCNTs significantly improves the tensile strength of the composites by 128% and 118% respectively, without compromising the elongation at break. Moreover, a 76% improvement in oxygen impermeability is observed for the 2% FCNTs. The chemical interactions between FCNTs and ENR 25 contribute to the excellent properties of the composites, which can be applicable in automobiles, packaging, and other demanding engineering sectors.

Summary: In this study, pyrolytic carbon (PyC) interlayers were introduced to improve the performance degradation in carbon fibers/carbon nanotubes (CFs/CNTs) multi-scale reinforced composites prepared by chemical vapor deposition (CVD) method. The combination of multi-scale reinforcements, lithium aluminosilicate (LAS) glass-ceramic, and PyC interlayers improved stress transfer, protected CFs from corrosion, and promoted synergy between components, leading to significantly enhanced mechanical properties. The flexural strength, fracture toughness, and work of fracture were significantly increased, making this study a valuable reference for related research in CFs/CNTs multi-scale reinforcements and LAS composites.

Summary: Three different blending procedures were used to create MWCNT/CR-NR composites. The effects of the blending process on the conductive network morphology, interfacial contacts, resistance-strain response behavior, and sensitivity of the composites were investigated. The results showed that the composites had a wide strain range and high repeatability in resistance-strain response. Different blending procedures had different effects on the morphology and interfacial interactions of the composites.
