Recent Developments of the Solution-Processable and Highly Conductive Polyaniline Composites for Optical and Electrochemical Applications

Abstract

Solution-processable conducting polymers (CPs) are an effective means for producing thin-film electrodes with tunable thickness, and excellent electrical, electrochemical, and optical properties. Especially, solution-processable polyaniline (PANI) composites have drawn a great deal of interest due to of their ease of film-forming, high conductivity up to 103 S/cm, excellent redox behaviors, processability, and scalability. In this review, basic principles, fabrication methods, and applications of solution-processable PANI composites will be discussed. In addition, recent researches on the PANI-based electrodes for solar cells (SCs), electrochromic (EC) windows, thermoelectric (TE) materials, supercapacitors, sensors, antennas, electromagnetic interference (EMI) shielding, organic field-effect transistors (OFETs), and anti-corrosion coatings will be discussed. The presented examples in this review will offer new insights in the design and fabrication of high-performance electrodes from the PANI composite solutions for the development of thin-film electrodes for state-of-art applications.

Biocompatible Electrospun Polycaprolactone-Polyaniline Scaffold Treated with Atmospheric Plasma to Improve Hydrophilicity

“…The morphology of PCL-PANI mats was characterized and compared to PCL mats ( Figure 2 ). The presence of PANI increased the solution conductivity and the charge density [ 57 , 58 ], causing two main changes in morphology of fibers: (i) the reduction in the average diameter of the fibers, caused by the electrical force that elongates the jet [ 33 ]; (ii) the formation of much thinner “spider-like” fibers, generated by the secondary jets [ 46 ]. FTIR spectra ( Figure 3 ) demonstrated the incorporation of PANI, by displaying both characteristic groups of PCL and PANI-CSA on the PCL-PANI mats.…”

The First Stages of Chemical and Electrochemical Aniline Oxidation—Spectroscopic Comparative Study

“…Polyaniline (PANI) is one of the most studied conducting polymers. It has a wide range of applications, including wastewater processing [1,2], catalysis [2], sensing [3][4][5][6], biomedical [5,7,8], optical [9] and electrochemical [9][10][11][12][13] applications. Many of these areas require PANI in the form of a thin film.…”

Flexible Methyl Cellulose/Polyaniline/Silver composite films with Enhanced Linear and Nonlinear Optical Properties

“…As observed, the MC absorption peak has increased with the addition of PANI. The two peaks of MC and PANI has also overlapped as a result of the blending process [18]. After the addition of AgNPs, a new adsorption peak characteristic for the surface plasmon resonance (SPR ) of the electrons of AgNPs is observed [19].…”

“…These results confirmed that the formed films have become more convenient to high rapid optoelectronic devices. The optical conductivity (σopt) which demonstrates the electrical conductivity that produced as a result of the charge carrier's transfer due to the variation in the electric field of the fallen electromagnetic waves has been determined from absorption coefficient ( ) using equation (18) [48]:…”
