Covalent Networks: 3D Nanocomposites of Covalently Interconnected Multiwalled Carbon Nanotubes with SiC with Enhanced Thermal and Electrical Properties (Adv. Funct. Mater. 31/2015)

Abstract

A novel approach for fabrication of 3D interconnected carbon nanotube (CNT)–silicon carbide composites is reported by M. Terrones and co‐workers on page 4985. The two‐step fabrication route involves coating CNTs with silicon oxide via a sol‐gel process, followed by spark plasma sintering, during which the SiOx is carbothermally reduced to SiC. A covalently interconnected SiC–CNT network composite with high thermal and electrical conductivities is created.

Light and Strong Hierarchical Porous SiC Foam for Efficient Electromagnetic Interference Shielding and Thermal Insulation at Elevated Temperatures

“…However, the fabricated hierarchical porous SiC foam in this study was a direct transformation from the carbon foam whose strength was high enough under the carbon thermal reaction. The continuous carbon thermal process from outside to inner resulted in covalently bonded SiC structure. , As a consequence, the struts of the macropore walls in hierarchical porous SiC foam could endure higher stresses without breakage.…”

Equilibrium structures of water molecules confined within a multiply connected carbon nanotube: a molecular dynamics study

“…21,22 In this paper, we report an MD study of the behaviour of water molecules inside a multiply connected carbon nanotubes (MCCNT). 23,24 MCCNTs could be produced by CNTs of different sizes clinging together under the influence of electronic beams to form Y-junctions, [25][26][27][28] in which a large CNT splits into two smaller CNT arms that eventually merge into one. Our study elucidates the structural arrangement of the water molecules inside these topologically complicated CNTs in detail, especially in the vicinity of the junction at which a CNT with a larger diameter is connected to two CNTs with a smaller diameter.…”
