Use of conductive polymer

One early program carried out at AUied-Signal, Inc. proposed the use of conductive polymers in remotely readable indicators (210). Conductivity changes induced in the conductive polymer could be read externally and the history of the sample known. Systems designed to detect time—temperature, temperature limit, radiation dosage, mechanical abuse, and chemical exposure were developed. 

The utilization of ionic liquids for the synthesis and use of conducting polymers brings together two of the most exciting and promising areas of research from recent years. 

However, to allow the widespread use of conducting polymers, more research is needed to improve their general performance, and one of their present limitations is the rapid degradation of key properties such as conductivity and electrochemical cydability. This limitation is primarily a result of the electrolyte used in the... 

This area covering the use of conducting polymers as Biosensors has been reviewed recently [24]. 

An active research area is currently the use of conducting polymers as OLED devices. These polymeric-organic electronic materials are varied in compositions. In 1957, the first intrinsic electrically conduction polymer. 

Nevertheless, several general papers have been published on stealth technology applied to aircraft such as LOCKHEED F 117 [5,6] or others [7,8,9]. The description of radar absorbing materials is restricted to iron or ferrite loaded paints or elastomers except the case of retinyl Schiff base salts [10,11]. This molecule attracted interest of many scientists in 1987. In fact this material which is a charge transfer salt derived from the A vitamin, never exhibited high-frequency dielectric constant due to its intrinsic conductivity, despite its beautiful orange colour Moreover, reference books as the one of Knott el al. [12] do not mention the use of conductive polymers for this purpose. 

All these findings contribute to new opportunities for the fabrication of flexible and efficient devices, with small dimensions, that may have potential applications for the fabrication of all-plastic sensing devices [34]. In particular, for strain/pressure sensors, the use of conducting polymers instead of metals allows to apply a pressure on the device without risks of irreversible damage to the contacts. 

So, there has also been considerable interest in the use of conducting polymers, particularly polypyrrole (PPy), polythiophene, and polyaniline (PANl), in the form of thin films or blends with conventional polymers as sensors for airborne volatiles such as alcohols, ethers, halogens, ammonia (NH3), NO2, and warfare simulants... 

Persaud and Travers [9] have summarized the main reasons for the use of conducting polymers as odor-sensing devices as follows ...
