What are advantages and Disadvantages of PEDOT?

Poly(3,4-ethylenedioxythiophene) or PEDOT (or sometimes PEDT) is a conducting polymer based on 3,4-ethylenedioxylthiophene or EDOT monomer. Advantages of this polymer are optical transparency in its conducting state, high stability and moderate band gap and low redox potential. A large disadvantage is poor solubility which is partly circumvented in the PEDOT-PSS composite, and the PEDOT-TMA material. (Note: Pedot is a transparent conductor. These conductors are used for LCDs and solar cells, among others.) PEDOT was making news in context with the T-shirts that tell us how our health is. It involved by applying a layer of gold nanoparticles to individual strands, along with the conductive polymer PEDOT.
