“…Nitrogen-containing carbon materials have received continuing interest in fields such as potential hydrogen storage media, [19a] electrodes for electric double layer capacitors, [19b] and catalyst supports. [15] That is to say, compared with PANI, the conjugation length of PBA decreased and the interchain distance increased. PBA has lower electrical conductivity (0.0751 S cm À1 ) than PANI [17a] because of the steric effect of the butyl group that induced additional deformations along the polymer backbone.…”

“…[6] Moreover, PANI derivatives [7] and copolymers [8] have been widely studied owing to their ease of preparation by chemical and electrochemical methods, good environmental stability, enhanced processability, optimizable electrical properties, and adsorbability. [13] The syntheses of poly(N-butylaniline) [14] and poly(aniline-co-N-butylaniline) [15] by both chemical and electrochemical polymerization have been reported. Until now, polychloroaniline, [9] polyethylaniline, [10] poly(N-ethylaniline), [11] and polyanisidine nanofibers, [9] and poly(N-methyl-A C H T U N G T R E N N U N G aniline) nanowires [12] were only synthesized and their application remains to be exploited.…”

Electroconductive poly(N-butylaniline)-lignosulfonate (PBA-LS) composite nanospheres were prepared in a facile way by in situ, unstirred polymerization of N-butylaniline with lignosulfonate (LS) as a dispersant and dopant. The LS content was used to optimize the size, structure, electroconductivity, solubility, and silver ion adsorptive capacity of the PBA-LS nanospheres. Uniform PBA-LS10 nanospheres with a minimal mean diameter of 375 nm and high stability were obtained when the LS content was 10 wt %. The PBA-LS10 nanospheres possess an increased electroconductivity of 0.109 S cm(-1) compared with that of poly(N-butylaniline) (0.0751 S cm(-1)). Furthermore, the PBA-LS10 nanospheres have a maximal silver-ion sorption capacity of 815.0 mg g(-1) at an initial silver ion concentration of 50 mmol L(-1) (25 °C for 48 h), an enhancement of 70.4% compared with PBA. Moreover, a sorption mechanism of silver ions on the PBA-LS10 nanospheres is proposed. TEM and wide-angle X-ray diffraction results showed that silver nanoparticles with a diameter size range of 6.8-55 nm was achieved after sorption, indicating that the PBA-LS10 nanospheres had high reductibility for silver ions.

“…This potential is related to the oxidation of monomers to radical cation, which is considered to be the first step in the polymerization of the conducting polymer. [33][34][35][36]38 The lower onset potential for the oxidation of pyrrole by comparison with 2-amino-4-phenylthiazole indicates that the oxidation of pyrrole is faster than that of 2-amino-4-phenylthiazole.…”

Electrochemical copolymerization of a binary mixture of pyrrole and 2-amino-4-phenylthiazole on platinum electrode in acid medium was carried out. The kinetic parameters were calculated using ex situ microgravimetric and electrochemical data. The experimentally obtained kinetic equations were R P,W ¼ k W [acid] 1.16 [monomer] 1.85 from microgravimetric data and1.1[monomer] 1.9 from the values of the anodic current density using cyclic voltammetry technique. The apparent activation energy was calculated by the two techniques and is found to be 32.55 and 29.6 kJ/mol from microgravimetric and electrochemical data respectively. The monomer reactivity ratios (r 1 and r 2 ) were calculated according to Fineman-Ross method and the copolymer structure was determined from the obtained data, which is found to be a block copolymer structure. The applications of the prepared copolymer as corrosion protection of mild steel in acid medium are studied.

“…The copolymerization of ANI with thiophene and the increase in the conductivity with increasing thiophene concentration were also investigated [32]. Furthermore, electrochemical copolymerization of ANI with aniline-2,5-disulfonic acid [33], o-aminobenzonitrile [34], m-phenylenediamine [35], N-butylaniline [36], and o-toluidine [36,37] are the examples of efforts to improve the properties of PANI. The copolymerization of o-aminophenol with ANI was studied by in situ spectroelectrochemical method in a detailed manner [38].…”

Copolymer of aniline and triethylene glycol bis(o-aminophenyl) ether was synthesized by constant potential electrolysis. Cyclic voltammogram of the copolymer films recorded in the monomer-free electrolytic solution revealed that the redox behavior of the films approaches to that of poly(triethylene glycol bis(o-aminophenyl) ether) with increasing amount of triethylene glycol bis(o-aminophenyl) in the feed ratio. Copolymerization was investigated by in situ recording the changes in the electronic absorption spectrum during electrolysis. The free standing copolymer film was characterized utilizing Fourier transform infrared spectrometer, and spectroelectrochemical behavior of the copolymer was investigated via in situ UV-vis spectroscopic technique. Besides the electron spin resonance study of the copolymer film, the different morphologies of the polymers were examined by scanning electron microscopy and the copolymerization was confirmed. The temperature dependence conductivity of the copolymer film was measured by four-probe technique in the temperature range of 100-300 K, and the calculated parameters showed that conduction mechanism fits to variable range hopping.
