What is conducting polymer?
Typical conducting polymers include polyacetylene (PA), polyaniline (PANI), polypyrrole (PPy), polythiophene (PTH), poly(para-phenylene) (PPP), poly(phenylenevinylene) (PPV), and polyfuran (PF) (Chart 1).
What are the types of conducting polymers?
Linear-backbone “polymer blacks” (polyacetylene, polypyrrole, polyindole and polyaniline) and their copolymers are the main class of conductive polymers….poly(pyrrole)s (PPY)
- poly(pyrrole)s (PPY)
- polycarbazoles.
- polyindoles.
- polyazepines.
What are conducting polymers Slideshare?
Conducting polymers are those polymers which conduct electricity due to extended P- orbital system. Due to this extension of P orbital electrons can move from one end to another end of the polymer.
What are conducting polymers give the classification and application of conducting polymers?
Conductive Polymers: Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The biggest advantage of conductive polymers is their processability, mainly by dispersion.
What are conducting polymers give example?
Examples include polyacetylene, poly(p- phenylene vinylene) (PPV), polythiophene, polypyrrole and polyaniline grafted derivatives (Ferraro, 1987). Polyacetylene derivatives: soluble poly(methylacetylene) and poly(phenylacetylene) have been synthesized (Yoshino, 1997).
What is the mechanism of conducting polymers?
The mechanism of electrical conductivity of conducting polymers is based on the transmission of polarons and bipolarons. The synthesis of conducting polymers can be accomplished by electrochemical polymerisation, which is more straightforward than traditional chemical synthesis.
What are conducting polymers and how they are classified?
Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The biggest advantage of conductive polymers is their processability, mainly by dispersion.
What are the properties of conducting polymers?
Conducting polymers are extensively studied due to their outstanding properties, including tunable electrical property, optical and high mechanical properties, easy synthesis and effortless fabrication and high environmental stability over conventional inorganic materials.
How are conducting polymers classified?
Conductive polymers are generally not thermoplastics, i.e., they are not thermoformable. But, like insulating polymers, they are organic materials. They can offer high electrical conductivity but do not show similar mechanical properties to other commercially available polymers.
What are conducting polymers how they are classified explain?
CONDUCTING POLYMERS : Polymers which can conduct electricity are called conducting polymers. Ordinary polymers obtained by usual methods are nearly insulators. However, some specific polymers may act as conductors. Classification: Conducting polymers may be classified as. POLYMERS.
Which of the following is conducting polymers?
Among well-known conducting polymers, polyacetylene and poly(phenylene vinylene) are synthesized almost exclusively by chemical polymerization or from precursor route. Polyheterocycles such as polythiophene or polypyrrole are synthesized by both chemical and electrochemical polymerization.
What are the applications of conducting polymers?
Applications of conducting polymers: 1. Conducting polymers are useful in discharging large quantities of static electricity in computer industries and in chemical industries. This can be accomplished by coating the conducting polymer over an insulating surface. Hence conducting polymers are used as antistatics. 2.
What are conductive polymers?
Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The biggest advantage of conductive polymers is their processability, mainly by dispersion.
What is doping of conducting polymer?
The effect of this oxidation or reduction on polymer is called doping, i. e. convert an insulating polymer to conducting one. Conducting polymers (CPs) such as polypyrrole, polythiophene and polyanilines are complex dynamic structures that captivate the imagination of those involved in intelligent materials research.
Who discovered conducting polymers?
6. Discovery of conducting polymers • Discovered in the late seventies (1977) by Alan Heegar , Dr. Hideki Shirakawa and Alan Macdiarmid. • Before that polymers were used as insulators in the electronic industry.
