“…PANI was synthesized by oxidative polymerization of aniline using H 2 O 2 generated from the AOx catalysed oxidation of alcohol. During this process, cation or cation radical sites generated in monomer (polymer) molecule initiated the polymer growth (Sapurina and Shishov, 2012). After 24 h of reaction time, the solution was centrifuged at 5000xg for 3 min.…”

“…Generally, aniline oxidation can yield different products as oligomers and oxidation products with an amino group in the ortho -position [16], which presents imperfections that might influence aggregate size. In addition, PANI properties were shown to be perturbed when monomers with amino group in the ortho -position were added to the synthesis solution [17,18,19].…”

The polyaniline/TiO2 (PANI/TiO2) composite photocatalysts were prepared by the in situ chemical oxidation of aniline (An) in the presence of TiO2 particles. For this purpose, photocatalysts with different amounts of PANI polymer were prepared and analysed. Fourier-transform infrared (FT-IR) spectroscopy and thermogravimetric (TG) analysis indicated successful synthesis of the PANI polymer and its conductivity was also determined. The micrographs of field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) were used to explain the impact of the aniline amount on the aggregation process during the synthesis of the composites. The smallest size of aggregates was obtained for the photocatalysts with 15% of PANI (15PANI/TiO2) due to the formation of homogenous PANI. The photocatalytic activity of studied PANI/TiO2 photocatalysts was validated by monitoring the discoloration and mineralization of Reactive Red azo dye (RR45) in wastewater. The 15PANI/TiO2 sample presented the highest photocatalytic efficiency under ultraviolet A (UVA) irradiation, in comparison to pure TiO2. This was explained by the formation of uniformly dispersed PANI on the TiO2 particles, which was responsible for the synergistic PANI-TiO2 effect.

“…However, its post-functionalization does not take advantage of PANI chains ability to self-organize into a variety of supramolecular structures [374][375][376]. To solve this issue, Rydzek et al recently introduced the Simultaneous Electropolymerization and ElectroClick functionalization (SEEC) of PANI (Fig.…”

No. of Pages 30 2 G. Rydzek et al. SummaryDuring the last few decades, electrochemistry and electrode modification have seen a tremendous fall off in creativity with the emergence of the nanoarchitectonic-based layerby-layer (LbL) film deposition technique. An unprecedented variety of building blocks can be immobilized on surfaces, leading to progress in several fields including sensing, electrochromic, electro-responsive and energy devices. This review describes the state of the art of electrochemical devices based on LbL assemblies, with a focus on supercapacitors, biosensors, and electroresponsive LbL such as electrodissolution/electroswelling of coatings. Recently, electrochemistry has also been used as an ''active trigger'' to induce the formation of films by covalent coupling, leading to new nanoarchitectonic approaches beyond the LbL strategy. These emerging electro-coupling reactions, including electroclick and carbazole chemistry, open new perspectives toward architecture and patterning of functional films and are extensively reviewed.
