Abstract:
Thin films of poly(methyl methacrylate)?multiwalled nanotubes composites were
produced by spin coating using different nanotube concentrations. The materials
were characterized by scanning electron microscopy, energy-dispersive x-ray analysis,
and Raman spectroscopy to obtain information on the possible interactions between the
constituents and to control the homogeneity of the films. Electrical conductivity
measurements of the composites, as a function of the nanotube concentration, show a
percolation threshold at very low concentration. Also, the

characteristics exhibits
a nonlinear behavior at low concentration, becoming linear far above the threshold.
