Fabrication of Carbon Nanotube Networks on Three-Dimensional Building Blocks and Their Applications
Three-dimensional (3D) networks of carbon nanotubes (CNTs) were fabricated on a pillarpatterned substrate by plasma-enhanced chemical vapor deposition (PECVD). To fabricate 3D networks of CNTs, highly crystalline single-walled CNTs (SWCNTs) should be synthesize on the substrate. PECVD has advantages for low temperature growth and alignment of CNTs on the substrate, but it is difficult to synthe...
متن کاملHigh density, vertically-aligned carbon nanotube membranes.
A method is presented to prepare high-density, vertically aligned carbon nanotube (VA-CNT) membranes. The CNT arrays were prepared by chemical vapor deposition (CVD), and the arrays were collapsed into dense membranes by capillary-forces due to solvent evaporation. The average space between the CNTs after shrinkage was approximately 3 nm, which is comparable to the pore size of the CNTs. Thus, ...
متن کاملApplications of three-dimensional carbon nanotube networks
In this paper, we show that it is possible to synthesize carbon-based three-dimensional networks by adding sulfur, as growth enhancer, during the synthesis process. The obtained material is self-supporting and consists of curved and interconnected carbon nanotubes and to lesser extent of carbon fibers. Studies on the microstructure indicate that the assembly presents a marked variability in the...
متن کاملNew Three-Dimensional Porous Electrode Concept: Vertically-Aligned Carbon Nanotubes Directly Grown on Embroidered Copper Structures
New three-dimensional (3D) porous electrode concepts are required to overcome limitations in Li-ion batteries in terms of morphology (e.g., shapes, dimensions), mechanical stability (e.g., flexibility, high electroactive mass loadings), and electrochemical performance (e.g., low volumetric energy densities and rate capabilities). Here a new electrode concept is introduced based on the direct gr...
متن کاملAligned carbon nanotube array stiffness from stochastic three-dimensional morphology.
The landmark theoretical properties of low dimensional materials have driven more than a decade of research on carbon nanotubes (CNTs) and related nanostructures. While studies on isolated CNTs report behavior that aligns closely with theoretical predictions, studies on cm-scale aligned CNT arrays (>10(10) CNTs) oftentimes report properties that are orders of magnitude below those predicted by ...
