Assembly and Interaction of Polyaniline Chains: Impact on Electro- and Physical–Chemical Behavior

Abstract

Polyaniline (PANI), is one of the promising candidates for utilization as electrode material in supercapacitors and its electro-and physical-chemical properties have been studied for several decades. However, there are fundamental questions that need to be answered. For example, is it possible to obtain and characterize individual PANI chains or what is the impact of

Electrochemical deposition of highly hydrophobic perfluorinated polyaniline film for biosensor applications

“…The spectra of the polymer lms obtained aer different electropolymerization durations evolve: with increasing duration, the absorption maximums are shied towards a longer wavelength and resemble the polaron band of polyaniline. [17][18][19][20] This is an important observation and signals the formation of the conductive form of the material. The low resistance of the deposited lm is conrmed below by electrochemical impedance spectroscopy (EIS).…”

One-step synthesis, characterization and properties of novel hybrid electromagnetic nanomaterials based on polydiphenylamine and Co–Fe particles in the absence and presence of single-walled carbon nanotubes

“…[4][5][6] The specic electronic structure of polymers with a system of polyconjugation determines their excellent electrophysical, optical and electrochemical properties. [7][8][9][10][11][12][13][14][15][16] The primary advantages of ternary nanocomposites are the synergistic effect between the three components, resulting in excellent electronic, optical, sensing, catalytic, magnetic properties, environmental and thermal stability. [17][18][19][20][21][22][23][24][25][26][27][28] Polymer-metalcarbon nanomaterials based on conjugated polymers can be used in magnetic information recording systems, for medical purposes, as electromagnetic radiation absorbing materials, to create sensors and nanoprobes, rechargeable batteries, and other electrochemical devices.…”

Electrochemically active water repelling perfluorinated polyaniline films

“…[14] These properties are strongly dependent on the morphology of the material as also the assembly and packing of the polymer chains. Recently, the interaction of the polymer chains leading to the formation of nanofibers resulted in very high values of capacitance in polyaniline as measured from galvanostatic charge discharge measurements by Tomšík et al [15] In this report, we are expanding our previous work on the polymerization of 3-perfluoroctyl aniline (3PFA) and 4-perfluoroctyl aniline (4PFA) by focusing on the insoluble polymer films that form at the interface between the organic and the aqueous phase and their electrochemical properties. We synthesized four polymer films -3PFA, 4PFA, and two 4PFA nanocomposites containing multi-wall carbon nanotubes (MWCNTs) synthesised using aerosol assisted chemical vapour deposition techniques.…”
