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.
