- Abstract
- We fabricated multiple-layered nonwoven multiwalled carbon nanotubes (MWCNT) sheets bymeans of treating MWCNTs with a spark plasma sintering process. We characterized the samples by Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy, and the field effect mobility method. Each thin nonwoven MWCNT layer is mainly comprised of interlocked, intertwined, or interconnected MWCNTs. XRD and Raman spectra coincidentally revealed that the graphitization occurred in the course of transformation from pristine to nonwoven MWCNTs. The multiple-layered nonwoven MWCNTs showed a higher electrical conductance than a single-layered nonwoven MWCNTs sheet. (C) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
