Abstract
A micromolding technique in capillaries was adapted to
make uniform patterns of polypyrrole (Ppy), and the conductivities
of the patterns were measured by direct contact IV curves
and conductance AFM methods. Noncovalently bound Ppy
patterns have high conductivity (low resistivity) before doping
and brittle characteristics. However, the covalently grafted Ppy
pattern shows relatively low conductivity and sticky viscoelastic
properties.
