Carbon Nanotube Sol−Gel Composite Materials

Abstract

This paper describes a new class of composite materials designed by combining multiwall carbon nanotubes (MWNTs) and sol−gels. These materials provide new capabilities for the development of electrochemical devices by taking advantage of the favorable electrochemical characteristics of MWNTs. Further, variations in the silane precursors used and in the carbon nanotube content of the composites results in materials with a range of capacitance, electron-transfer rates, and potential to control selectivity.

Functionalized carbon nanotubes and nanofibers for biosensing applications

“…In the non-aligned approach, CNTs are randomly immobilized on the electrode surface by physical adsorption (e.g., casting or spin casting) and composite entrapment using polymer [18,19] and sol-gel [20].…”

Direct growth of vertically aligned carbon nanotubes on silicon substrate by spray pyrolysis of Glycine max oil

“…The I D /I G value of as grown CNTs is 0.858. Generally, lower I higher degree of graphitization [3 The as grown CNT sample was characterized by XRD. Figure 4 shows the XRD CNTs grown at 650 °C.…”

“…Aligned carbon nanotubes represent an important architecture of CNTs because they can be used directly as field emitters in flat panel displays as reinforcing agents in composite materials [2,3]. Furthermore, vertically aligned carbon nanotubes also exhibit a high capability to produce high current densities under low operating voltages [4].…”

Development and Characterization of Nanobattery Systems

“…Recently, Bachas and co-workers [2] incorporated carbon nanotubes to enhance electrical properties of sol-gel materials and we incorporated bundles of CNTs in battery cathodes where enhanced performance was observed. The addition of carbon nanotubes in a dispersed state to the V 2 0 5 sol-gel studied here should increase the electrical conductivity in the resulting xerogel composites.…”
