With the needle-circle electrode configuration, two-dimensional(2-D) P
olypyrrole(PPy) with a fractal pattern was electropolymerized under a
mica which was set on the electrolyte solution surface. The mica serve
s as a sample of the induction substrate to support the growth of PPy.
The results provide a new way to obtain 2-D PPy and have prospect in
research and practice.
