Conductive plastic

Hello friends, my name is Arjun Gupta and today we learn about "Conductive plastic". If I say what is a conductor, you will say, those who conduct electricity or if, I say what is an insulator, you will say, those who don't conduct electricity, and the last one is semiconductor which acquires both the property of conductor and insulator, at a certain temperature.

Many years ago, the conductive plastic was discovered  "Accidentally" by USA scientists.

The conductive plastic is flexible in nature as well as show conductive property.
Example of conductive plastic is PEDOT.
         poly(3,4-ethylenedioxythiophene)

This technology helps to make flexible phone and T.V. and many more electronic products.

Conductive plastic is usually used in ESD (electrostatic discharge) control, as well as ATEX (explosive atmosphere) and EMI (electromagnetic interference) shield applications. Other uses of conductive plastics include prevention of metal replacement solutions, level detection sensors, heating elements, air cleaning systems, dust suppression and electrostatic attractiveness (ESA).



By ensuring that any plastic material is electrically conductive, we can eliminate the problems caused by electrostatic discharge, making the world a more comfortable and safe place for all of us!

A conductive material, because it has less electrical resistance, allowing electrons to flow smoothly on its surface or through its volume. Conductive materials have less electrical resistance, usually less than 1 x 105 OHMS/square and 1 x 104 ohm-cm. When a conductive material is charged, the charge will be evenly distributed on the surface of the material. If the charge conductive material makes contact with any other conductive material, the electron will be easily transferred between the contents. If the second conductor is connected to the earthing point of the earth, then the electron will flush over the ground and the extra charge will be neutralized on the conductor.

Electrostatic charge can be made of turbo-electrically on the conductor as it is made on the insulator. As long as the conductor is different from the other conductor or the ground, the stationary charge will remain on the conductor. If the conductor is loaded on the ground then the charge will easily go to the ground. Or, if the charging conductor contacts or near any other conductor, the charge will be swept between two conductors.



Plastic has many advantages over other materials. In relation to potentially explosive atmospheres, however, the non-conductive properties of the plastic should be kept in mind. Due to this property, there is a threat of stable development. If such charge material discharges due to sparking, then they can cause explosive atmospheres, such as a mix of solvents and air or dust and air mixture, to explode. These types of plastics cannot be used in such applications. To take advantage of plastic benefits such as polyethylene or polypropylene for those areas of applications, special types of carbon are added, the so-called conductivity carbon. As a result, their conductivity is very high, i.e. their electrical resistance is very low. Due to this caution, the electrochemical quantity of PE can be reduced, for example, from 1016 ohms to <106 ohms.



Plastics are able to discharge electricity. If they are in the soil, then a stable charge can be reliably preventable. In addition to lack of volume resistivity, black staining also provides excellent UV protection, for example in the case of electrically conductive polyethylene (PE-EL).
