solution (50 ml) of pyrrole (0.1 M) and NaClO 4
(0.1 M) is added to the cell. A potential sweep
from −0.6 V vs. SCE to +0.8 V vs. SCE at a scan
rate of 100 mV s −1 involves polymerization on
the working electrode, which is monitored as
shown in Figure A.3 . The working electrode
covered with polypyrrole is purified by washing
with water.
