What is the conductivity of polyaniline?

Undoped polyaniline has a conductivity of 6.28×10−9 S/m, whereas conductivities of 4.60×10−5 S/m can be achieved by doping to 4\% HBr. The same material can be prepared by oxidation of leucoemeraldine.

Which material has the highest electrical conductivity?

Silver
Silver has the highest electrical conductivity of all metals. In fact, silver defines conductivity – all other metals are compared against it. On a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76.

What gives a high level of electrical conductivity?

Silver also has the highest thermal conductivity of any element and the highest light reflectance. Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance.

What mineral has the highest electrical conductivity?

As a result, silver is by far the most conductive metal on Earth. This is because silver only has one valence electron. In addition, this single electron is free to move around with little resistance. As a result, metals like silver and copper are a few of the metals with this particular characteristic.

How do you increase polyaniline conductivity?

conductivity of polyaniline depends on a number of synthesis parameters.

1. 1.It is reported that dopants like bulky dopant like camphor sulphonic acid could improve the conductivity . so try another dopant.
2. remove oligomers by repeated solvent extraction.
3. try interfacial polymerisation.

What is polyaniline structure?

Polyanilines are a class of conducting polymers which can exist in three different oxidation states, namely the completely reduced leucoemeraldine base, the completely oxidized pernigraniline base, and the emeraldine base consisting of alternating oxidized and reduced repeat units in its structure.

What is the best electricity conductor?

What Metal is the Best Conductor of Electricity?

• Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity.
• Copper. One of the most commonly used metals to conduct electricity is copper.
• Aluminum.

Which of the following has the highest conductivity?

The correct answer is Silver. Silver has the highest conductivity of all metals.

Why is polyaniline used as a conducting layer in OLED?

… Among them, conducting polyaniline (PANI) [1,2] is one of the most studied and promising conducting polymers due to its environmental stability, low cost and good electrical conductivity. This polymer can be used for the metallic parts in components like capacitors, displays, light-emitting diodes, etc.
