A current-induced localized heating technique for fabrication of carbon nanomaterials

Abstract

A commercial copper clad laminate was used to fabricate the carbon nanomaterials using a localized heating technique. The surface Cu layer was patterned to a Cu trace and served as a localized heating source as it was current-stressed. Thermal decomposition of phenol formaldehyde, which was the primary constituent of the bottom paper phenolic board, took place primarily near the Cu trace and the carbon nanomaterials were formed directly on the board. The products contain carbon nanosheets and tubular carbon nanofibers. (C) 2009 Elsevier B.V. All rights reserved.
