Carbon fiber reinforced carbon composites (Cf/C) were first joined by combining electric field-assisted sintering technology and using a Ti3SiC2 (TSC) tape film as interlayer. A joint with shear strength of 26.3 ± 1.7 MPa was obtained within 12 min at a joining temperature of 1200 °C. The joint morphology, interface reaction, shear fracture behavior, and joining mechanism were investigated in detail...
A small amount of graphene oxide (GO) was introduced into poly(vinylidene fluoride) (PVDF)/carbon nanotube (CNT) composites through solution compounding. The thermal conductivity, crystallization behavior of PVDF matrix, and the dispersion states of CNTs and/or CNT/GO in the PVDF composites were comparatively investigated. The results demonstrated that with the presence of only 1wt% GO, the PVDF/CNT/GO...
The rational integration of conductive nanocarbon scaffolds and insulative sulfur is an efficient method to build composite cathodes for high-energy-density lithium–sulfur batteries. The full demonstration of the high-energy-density electrodes is a key issue towards full utilization of sulfur in a lithium–sulfur cell. Herein, carbon nanotubes (CNTs) that possess robust mechanical properties, excellent...
Pt and Pd–Pt nanoparticles were anchored on reduced graphene oxide (RGO) with the aid of poly(diallyldimethylammonium chloride) (PDDA), where Pt and Pd ions were first attached to PDDA-functionalized graphene oxide sheets and the encased metal ions and graphene oxide were then reduced simultaneously by ethylene glycol. As supported by transmission electron microscopy, metal nanoparticles, of small...
