Özet:

 


                        In this paper, we report a simple, low-cost, and 
environmentally friendly electrochemical method to obtain a novel copolymer 
consisting of 1-pyrenyl-2,5-di(2-thienyl)pyrrole and pyrrole on a pencil 
graphite electrode (PGE). 
Poly(1-pyrenyl)-2,5-di(2-thienyl)pyrrole-co-pyrrole) that is P(PyrPy-co-Py) 
film was prepared by one-step potentiostatic codeposition in an ethanol 
solution containing PyrPy and Py monomers for supercapacitor applications. 
The electrodeposition of homopolymer and copolymer modified electrodes was 
carried out on the surface of the PGE via chronocoulometry. For comparison, 
P(Py)/PGE and P(PyrPy)/PGE were also electrochemically synthesized under the 
same reaction conditions. The surface morphologies of all the electrode 
materials were analyzed by field emission scanning electron microscopy. The 
capacitive properties of the modified PGEs were investigated in 1 M 
H2     2    22_{2}SO4     4    44_{4} electrolyte solution by cyclic voltammetry, electrochemical 
impedance spectroscopy, and galvanostatic charge-discharge methods. Compared 
with P(Py)/PGE and P(PyrPy)/PGE, the P(PyrPy-co-Py)/PGE composite exhibited 
the best electrochemical behavior and had the highest specific capacitance 
value of 397.18 F g−1    −  1   −1−1^{-1} in 1 M H2     2    22_{2}SO4     4    44_{4} at a scan rate of 2 mV 
s−1    −  1   −1−1^{-1}. These results indicated that this modified electrode can be used 
as an electrode material for electrochemical supercapacitors.
