Nonlinear current-voltage (I-V) characteristics are important for creation of organic
semiconducting devices. Three classes of nanocomposites are considered in this presentation:
polyurethane (PU)/single wall carbon nanotubes (SWNT) self-organized thin films; 2D percolative
network of polyaniline (PANI) in surface-modified poly(vinylidene fluoride) (PVDF); and polymer
core-shell latex systems (PANI/PVDF). All systems under consideration are also suitable for printed
electronics applications. Structure-properties relationships for semiconducting nanocomposites are
studied with several modes of atomic force microscopy, namely, traditional topography imaging and
ultrasonic force microscopy (UFM), Raman spectroscopy, and surface conductivity characterization.
