Carbon Nanotube Sol−Gel Composite Materials

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.
