Revealing distortion of carbon nanotube walls via angle-resolved Xray spectroscopy
M.A. Kanygin,A.V. Okotrub,L.G. Bulusheva,O.Y. Vilkov,K. Hata 한국물리학회 2015 Current Applied Physics Vol.15 No.10
Arrays of aligned single-walled carbon nanotubes (SWCNTs) produced by supergrowth method were studied by scanning electron microscopy (SEM) and angle-resolved near-edge X-ray absorption fine structure spectroscopy, which defined that nanotube disorder is 10e13 and 23e27, respectively. The latter value was confirmed by X-ray fluorescent spectroscopy. The difference in the obtained angular deviations was attributed to distortion of the SWCNT walls, because the X-ray spectroscopy methods are sensitive to a local environment of probing atoms, while the SEM examines the nanotubes at a substantially larger length scale. Significant distortion (20e24) of SWCNT walls could be related to the defects introduced during the growth process.

Multiwall carbon nanotubes (MWNT) were produced using the arc-discharge graphite evaporation technique. Composite films were developed using MWNT dispersed in polystirol polymer. In the present work, various properties of the polymeric thin film containing carbon nanotubes were investigated by optical absorption, electrical resistivity and the same have been discussed.
