Abstract
Flexible, transparent and conducting poly(methyl methacrylate) (PMMA)
composites films were prepared using SOCl2 functionalized SWNTs.
Optical absorption spectra measured on composite films confirm that the
composite preparation procedure preserves the electronic properties
(position of the Fermi level) of the p-doped nanotubes in the polymer
matrix. Due to the doping effect of SOCl2 the electrical conductivity
of the composites is improved by a factor of 5. The light transmission
of the composite films depends on the film thickness and on the
nanotube concentration. The optical transmittance of visible light at
500 nm was found to be 92% for 0.1 wt% SWNT loading and 46% for 0.5 wt%
SWNT loading. The thickness of the specimens was approximately 20 gm.
Conductivity measurement of the thin films performed with the four lead
method revealed values 3.5 x 10(-3) S/cm and 4.7 x 10(-1) S/cm,
respectively. (c) 2006 WIELEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
