Conducting Polymers: Concepts and Applications

Journal of Atomic, Molecular, Condensate and Nano Physics, 2018

The developments in the field of electrically conducting polymers have grown very rapidly since the discovery and there is a very sharp increase in conductivity when intrinsically insulating organic conjugated polymers are doped with oxidizing and reducing agents. An overview of technological developments involving conducting polymers clearly indicates that the field expands at unprecedented rates. The manuscript first introduces the conducting polymers (CPs), conducting mechanism, concepts of doping and briefly introduces main applications. Different types of CPs, their unique properties and synthesis is discussed. The present review will help the effective implementation of conducting polymers in different fields, which directly depends on the degree of understanding of their behaviour and properties.

Synthesis and Characterization of Conducting Polymers: A Review Paper

2014

Polymers are long chains of repeating chemical units called monomers. They share several characteristics including macro and micro properties, electrical transport properties, semiconducting properties and optical properties. Polymers can be synthesized by chemical and electrochemical polymerization. Polymers prepared through these methods can also be characterized by their electrical, optical, mechanical and electrochemical means.

Conducting Polymers and their Applications

Current Physical Chemistrye, 2012

This review article focuses on conducting polymers and their applications. Conducting polymers (CPs) are an exciting new class of electronic materials, which have attracted an increasing interest since their discovery in 1977. They have many advantages, as compared to the non-conducting polymers, which is primarily due to their electronic and optic properties. Also, they have been used in artificial muscles, fabrication of electronic device, solar energy conversion, rechargeable batteries, and sensors. This study comprises two main parts of investigation. The first focuses conducting polymers (polythiophene, polyparaphenylene vinylene, polycarbazole, polyaniline, and polypyrrole). The second regards their applications, such as Supercapacitors, Light emitting diodes (LEDs), Solar cells, Field effect transistor (FET), and Biosensors. Both parts have been concluded and summarized with recent reviewed 233 references.

Electrical Properties of Different Polymeric Materials and their Applications: The Influence of Electric Field

Properties and Applications of Polymer Dielectrics, 2017

In this chapter, a comprehensive study on the general structure of polymers, their properties and applications has been carried out. In particular, the application of polymers for insulating high-voltage (HV) equipment has been reported, together with the effect of electric field when they are subjected to HV stress. Experimental results related to the effect of partial discharge (PD) on polymeric insulations have been reported and discussed. Practical implications of the results have been discussed, and recommendations are made for future improvement. It is important to obtain new information regarding novel polymeric materials such as nano-polymers that can possibly outperform the currently used ones. It is also vital to investigate the right information for electrical equipment, i.e. by using the appropriate polymer as solid insulation, minimizing the presence of any metallic sharp object and any other conducting path during manufacture in order to avoid any type of internal or external PD.

Conducting Polymers: Properties and Applications

Journal of Intelligent Material Systems and Structures, 1994

There are over 100 conducting polymers which have been synthesised by chemists with a wide range of specific electrical conductivities. Many of these polymers are suitable for elec tronic device fabrication. Semi-conducting and conducting polymers have potential for application in several areas. In this paper electronic and microwave properties are explored. Fabrication of elec tronic and microwave devices can be

Synthesis of conducting polymers and their characterization

2010

Nanostructures of conducting polymer (polypyrrole) have been fabricated by chemical synthesis using non-galvanic method within the pores of polycarbonate membrane. Polycarbonate (Makrofol KG) foil of thickness 10 µm and diameter 100 nm having flux 10 5 /cm 2 purchased from Whatman, UK has been used as template for the fabrication of polypyrrole nanostructures. The morphology of the structures has been studied by scanning electron microscope (SEM).

Physical Principles of the Conductivity of Electrically Conductive Polymer Composites (Review)

Molecular Crystals and Liquid Crystals, 2012

The role of the structural peculiarities of electrically conductive polymer composites is considered in this review. Different conceptions of the nature of the conductivity and the mechanisms of charge transfer in heterogeneous structures are presented. Experimental results obtained by different scientists are only partially in accord with existing theoretical models. It is suggested that lack of information on various physical

SYNTHESIS AND CHARACTERIZATION OF CONDUCTING POLYMER NANOCOMPOSITES

Polymers have always been considered as insulators of electricity. No one would have believed 30 years ago that polymers could conduct as good as metals. Electrically conducting polymers combine the electrical properties of metals with the advantages of polymers such as light weight, greater workability, resistance to corrosion and chemical attack and the lower cost and have infiltrated our day to day life with a wide range of products, extending from most common consumer goods to highly specialized applications in space, aeronautics, electronics and nonlinear optics. The main aim of this project is to synthesize a polymer nano-composite which has good mechanical strength as well as good electrical properties and to study the properties of the specimen with change in percentage of salt and nano-powder. Polyvinyl Pyrrolidone a water soluble polymer will be used as a base polymer material and potassium or ammonium iodide will be used as doping agent. Alumina, aluminum nitride & nickel oxide (<50nm) nano-powder will be used to increase mechanical strength and dielectric properties of the specimen.
