“…The surface of PANI film is quite rough because the electrochemical polymerization of PANI from aniline is a two-stage growth process. Firstly, a dense and compact layer of PANI appeared on the bare electrode and then PANI grows anisotropically to form a loosely bound structure [41,42].…”

Silver and polyaniline (Ag/PANI) composite counter electrodes (CEs) have been prepared by electrochemical polymerization on stainless steel substrate using different silver (Ag) concentrations for dye-sensitized solar cells (DSSC). The effect of Ag concentration on the properties of fabricated Ag/PANI composite CEs, such as morphology, electrical conductivity, oxidation and reduction potential, and electrochemical activity of I 3 -reduction, is investigated. Highest cathodic current density (3.4 mA), low charge transfer resistance (2.15 X), and good electrocatalytic activity of I À 3 =I À redox couple for CE are obtained at 0.07 M concentration of silver in Ag/PANI composite. DSSC based on this CE shows best photovoltaic performance with conversion efficiency up to 7.31 %. This study indicates that the Ag/PANI composite prepared electrochemically is possible substitute of the expensive Platinum as CEs for DSSCs.

“…On the other hand, the large molecular chain structure of anionic polyelectrolyte makes it more difficult to be removed from the conducting polymers than the small molecule acid, exhibiting a better stability once being doped in conducting polymers (Nguyen and de Vos 2004). In recent years, several works have demonstrated that using sodium alginate (SA) (Li et al 2011;Sahoo et al 2012), carboxymethylcellulose sodium (CMC) (Basavaraja et al 2012;Chou et al 2011;Peng et al 2012), poly(sodium-4-styrenesulfonate) (PSSNa) , and phosphorylated polyvinyl alcohol (PPVA) (Yang et al 2014) in the preparation process, various nanostructures of conducting polymers could be obtained.…”

The size-controllable polypyrrole (PPy) nanospheres are successfully synthesized by oxidative polymerization of pyrrole using N-methylene phosphonic chitosan (NMPC) as a structure-directing agent. By simply changing the amount of NMPC, the size of the PPy nanospheres can be adjusted from 190 to 50 nm in diameter. The spectrometric results suggest that the electrostatic interactions of phosphate groups in NMPC molecule with pyrrole ring might be a driving force for formation of the uniform and sizecontrollable PPy nanospheres. The PPy nanospheres with the diameter of 100 nm exhibit the largest capacity and a good cycling stability as electrode materials of supercapacitors. The as-prepared PPy nanospheres also can be combined with carbon dots to form composite nanospheres presenting enhanced fluorescence intensity, which show potential application in fluorescence detection.

“…However, the specific capacitance of PANI with dense morphology is still limited by low ionic transport through its film while the stability of thin film (a few micrometers in thickness) of PANI is somewhat poor [4]. The conductivity of pure PANI is rather low (2 S cm À 1 ) [5] when compared with polypyrrole (55-100 S cm À 1 ) [6], polythiophene (300-400 S cm À 1 ) [7], and PEDOT (300-500 S cm À 1 ) [7] leading to low charge transfer in PANI pseudocapacitors.…”
