“…However, this electrocatalytic activity will affect the electrochemical system even in subsequent cycles. Similar behavior was also detected for simultaneous chemical and electrochemical polymerization of aniline, where the chemical reaction assists the initial polymer growth without needing the initial monomer oxidation on the substrate electrode 42. Note that Ni nanostructures have been partially formed on the carbon nanotube added, and its role is different from graphite powder as a conductive agent, as this issue will be discussed.…”

Electrochemical polymerization of aniline on nanostructured Ni substrates was investigated. To this aim, the Ni substrate electrodes were prepared by casting various samples of Ni nanoparticles having different morphologies. The electropolymerization on these different nanostructured Ni substrates was systematically investigated by means of comparative results obtained from cyclic voltammetry and electron microscopy as representatives of electrochemical behavior and morphology, respectively. Since the Ni nanoparticles are the beginning sites for the polymer growth, polyaniline morphology is strongly controlled by the nature of the Ni nanoparticles associated with chemical properties rather than geometrical shape. In conclusions, although the substrate surfaces had a similar nanostructure, but due to the difference in their chemical properties, the morphologies electrochemical behaviors of the polyaniline films electrodeposited on these substrates are significantly different.

“…As a result, many technological applications have been demonstrated, with PANI widely used as a base material in the development of pH sensors, biosensors, rechargeable batteries, supercapacitors, electrochromics, electromagnetic shielding, light emitting devices, photovoltaics, electrostatic discharges, and corrosion‐protecting coatings . Despite the vast bibliography devoted to PANI, new studies focusing on the polymerization process are reported each year …”

A novel, efficient, and easily synthesizable catalyst, an emeraldine form of polyaniline (PANI)21-hydroxyethane 1,1-diphosphonic acid salt (HEDP), was successfully synthesized and demonstrated as a reusable polymer-based solid acid catalyst in the synthesis of N-benzylidine-2-phenyl imidazo[1,2-a]pyridines with 2-aminopyridine with aromatic aldehydes and trimethyl silylcyanide at room temperature. PANI-HEDP was characterized by Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, field emission scanning electron microscopy, and conductivity measurements.

In this work, three polymeric films derived from hydroxyphenylacetic acid isomers were electropolymerized onto the surfaces of graphite electrodes through cyclic voltammetry. Analysis of electrochemical behaviors and electrical properties of the three polymeric films were investigated and their probably structures were explored by molecular modeling. The best functionalization strategy for the incorporation and retention of adenine and guanine nitrogenous bases was the poly(3-hydroxyphenylacetic acid). It was applied for the immobilization of a nucleotide probe specific to DNA of the bacteria Neisseria meningitidis operated in amperometric and impedimetric indirect modes. The simple protocol of electrochemical detection of DNA by the bioelectrode, developed in this work, could be further enhanced and applied in a low-cost and pain-less platform to diagnose human meningitis infection.
