Abstract:
Organic thin film nanocomposites, prepared by liquid-
phase exfoliation, were investigated for their superior
electrical properties and thermoelectric behavior. Singlewalled
carbon nanotubes (SWNT) were stabilized by intrinsically
conductive poly(3,4-ethylenedioxythiophene):poly(styrene
sulfonate) (PEDOT:PSS) in an aqueous solution. The electrical
conductivity (r) was found to increase linearly as 20 to 95 wt
% SWNT. At 95 wt % SWNT, these thin films exhibit metallic
electrical conductivity ( 4.0 105 S m 1) that is among the
highest values ever reported for a free-standing, fully organic
material. The thermopower (S) remains relatively unaltered
as the electrical conductivity increases, leading to a maximum
power factor (S2r) of 140 lW m 1 K 2. This power factor
is within an order of magnitude of bismuth telluride, so it
is believed that these flexible films could be used for some
unique thermoelectric applications requiring mechanical flexibility
and printability.
