Organic chemistry
Since the invention of the first synthetic polymer product, bakelite, synthetic polymer products have frequently been invented.

Polypyrrole (PPy) is a conducting polymer formed by oxidative polymerization of pyrrole. A suitable oxidizing agent is iron (III) chloride (FeCl3). Water, methanol, ethanol, acetonitrile and other polar solvents may be used for the synthesis of PPy. As a solid conducting polymer electrolyte It reaches conductivities up to 100 S/m. Polypyrrole was the first conductive polymer used in polymer Al-e-caps as well as in polymer Ta-e-caps.
