WebSep 2, 2024 · Poly(3,4-ethylenedioxythiophene) (PEDOT) is one of the most important conductive polymers utilized in a variety of applications in organic electronics and bioelectronics and energy storage. PEDOT chains are believed to be rather short, but detailed knowledge of their length is missing because of the challenges in its … WebPolymer chemistry is an example of applied organic chemistry. Polymers are long chain macromolecules built from repeated smaller chemical structures or ‘-mers.’ They are found widely in the natural world (e.g. proteins, rubber, cellulose) and, increasingly the past century, in synthetic form (e.g. “plastics”).
