J Mater Chem B 1:1340–1348. Segmented conducting polymers based upon a calix[4]arene scaffold are reported. It is observed that the addition of nanoparticles has significant influence on changing structural parameters and hence enhancing the conductivity of the polymer composite considerably. One problem is that, due to the presence of this ex-tended conjugation along the polymer backbone, the chains are rigid and possess strong interchain interactions resulting in in-soluble and infusible materials. Main results: A range of charge density and impedance responses were seen with each respectively doped conducting polymer. The four main methods of doping are Conducting Polymers conducting. Usually the partial reduction of a polymer results in an n-doping of the polymer. This is followed by an in depth exploration of the synthesis, properties and utilization of several types of self-doped polymers. Classification of Conducting Polymers: The conduction of electricity in this type of polymers is due to conjugation in the backbone of the polymer. It is a well know conductive polymer as its discovery started the development of (doped… It has been found that doped ions in the conducting polymer are hydrated, and hydration is strong for cations, which is commonly known in aqueous electrolytes. The conjugation can be due to either pi electrons or due to doped ingredients. Pravin H. Wadekar. Lightly doped poly(3-alkylthiophene) exhibits the characteristics of a polymer gel.
