What is the Difference Between Conducting and Non Conducting Polymers?

🆚 Go to Comparative Table 🆚

The key difference between conducting and non-conducting polymers lies in their ability to conduct electricity. Conducting polymers are materials that can conduct electricity, while non-conducting polymers are electrically insulating materials. Here are some key points to differentiate between the two:

  • Conducting Polymers: These polymers have backbones of contiguous sp2 hybridized carbon centers, allowing them to conduct electricity. One valence electron on each center resides in a pz orbital, which overlaps with neighboring orbitals, forming a continuous π-band that allows electron transport. Examples of conducting polymers include polyacetylene and polyaniline.
  • Non-Conducting Polymers: These polymers do not have the ability to conduct electricity. They are mainly used as insulating materials in various applications. Examples of non-conducting polymers include polyethylene and polystyrene.

In summary, the primary difference between conducting and non-conducting polymers is their ability to conduct electricity, with conducting polymers having contiguous sp2 hybridized carbon centers that allow for electron transport, and non-conducting polymers lacking this structure.

    The main difference between conducting and non-conducting polymers is their ability to conduct electricity. Here is a table comparing the key differences between conducting and non-conducting polymers:

    Property Conducting Polymers Non-Conducting Polymers
    Electrical Conductivity Can conduct electricity due to the presence of extended π conjugation along the molecular backbone Cannot conduct electricity, as they lack extended π conjugation
    Electrochromic Properties May display electrochromic properties, causing color changes due to redox transformations Usually do not display electrochromic properties
    Applications Used in organic printable electronics, such as OLEDs and organic photovoltaics (OPVs) Limited applications in electronic devices
    Processing Easy to process, mainly by dispersion May require different processing techniques

    Conducting polymers, such as poly(3-alkylthiophenes), are widely used in solar cells and transistors. Non-conducting polymers, on the other hand, have more limited applications in electronic devices.
