An electrochemical quartz crystal microbalance study on polymerization of oligo-p-phenylenes

AC Impedance Studies on the Relationship between the Fractal Characteristics and Electrochemical Properties of Poly(Para‐Phenylene) Film

“…The decrease in growth, which had been observed from other conducting polymers, 25 is associated with a polymerization holdback due to oxidative degradation and/or increasing resistance of the PPP coating during the polymerization process. As for the maximum of Qc values moving to a small number of scans with the increase in times the electrolyte is used may be explained by degradation of the electrolyte which is due to the increase of the acid produced by radical coupling 26 and the trace water absorbed from the environment for every time the electrode is replaced.…”

Influence of the nature of the supporting electrolyte on the formation of poly[4,4′-bis(butylsulphanyl)-2,2′-bithiophene] films. A role for both counter-ion and co-ion in the polymer growth and p-doping processes

“…The so-called Ôsensitivity constantÕ C f is equal to 11.32 Hz ng À1 for the crystal employed in this work. Calibration of the quartz crystal microbalance and evaluation of the piezoelectric active area were performed by silver electrodeposition under potentiostatic conditions [15,16,20,44]. The electrochemical charge used in any electrodeposition process is somehow linked to the mass change occurring at the electrode surface, i.e., to the electrode mass change.…”

“…[14][15][16][17][18][19][20][21][22][23]. Furthermore, numerous CP films have been investigated by EQCM and many mechanistic and thermodynamic insights into their behaviour have been reported [18,[22][23][24][25][26][27][28][29][30][31][32][33][34].…”

Electrochemical polymerization of p‐terphenyl in mixed electrolyte of boron trifluoride diethyl etherate and CH2Cl2

“…PPP has been synthesized from benzene and its derivatives by using various methods 10–22. In the early stages of research, however, it was not easy to make a PPP film for its characterization and application because PPP powders synthesized chemically were not soluble in most organic solvents, and electrochemical synthesis of PPP using benzene as a monomer also required harsh experimental conditions 13–15.…”
