Conducting polymer: silver interface, morphology and properties (original) (raw)

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.

Advances in sensors based on conducting polymers

Journal of Scientific & Industrial Research, 2006

Conducting polymers with a blend of interesting optical and mechanical properties can be used in situations where inorganic materials are not suitable. Synthetic capabilities as well as fabrication techniques have been developed to such an extent that molecular electronic devices based on conducting polymers can be designed, marking evolution of a sophisticated technology in the field of microelectronics. These electro-active conducting polymers cover a broad spectrum of applications from solid-state technology to biotechnology and sensor technology. Present paper addresses the various issues on sensors for chemical and biochemical species.

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.

Conducting Polymer Electronics

Journal of Intelligent Material Systems and Structures

Before conducting polymers can be employed in many applications, some of the intrinsic properties of these materials need to be better understood. An overview of the research and development of conducting polymers being undertaken at UTS is presented. Because conducting polymers are difficult to process once fabricated, an understanding of synthesis parameters and the use of synthesis techniques to produce conducting polymer films with desired properties is of the upmost importance. Descriptions of the galvanostatic and potentiostatic techniques employed to produce polyheterocyclics are presented. Thermal properties such as thermal diffusivity, thermal conductivity and specific heat are being investigated. Preliminary results reveal that the thermal diffusivity of polypyrrole is higher than that achieved with traditional polymers. The nature of contacts and junctions with polypyrrole and poly(3-methylthiophene) are discussed. High work function metals form ohmic junctions with polypyrrole while aluminium forms a Schottky barrier with poly(3-methylthiophene). Microwave studies on polypyrrole films reveal that the microwave transmission and reflection are dependent upon the doping level of the film. Applications of the conducting polymers in data security modules and for light weight electrically conducting wires are also illustrated.
