Common conductive polymers include:
Polyacetylene: Known for its simple structure and high conductivity, although its stability in air is challenging, high conductivity can be achieved through iodine doping and oriented stretching.
Polythiophene and polypyrrole: As variants of polyacetylene, their hydrogen atoms are replaced by sulfur or NH. While their conductivity is slightly lower than polyacetylene, their stability is better, making them particularly suitable for the manufacture of electronic devices.
Polyaniline: Synthesized as early as 1910, it was known as "aniline black." Truly high-conductivity polyaniline is obtained through the oxidative polymerization of aniline monomers in acidic aqueous solutions. Polyaniline is highly attractive in many fields due to its structural diversity, excellent physicochemical properties, stable properties, and simple preparation process.
