3.Application
As the monomer of conducting polymer, EDOT is mainly used to synthesize conducting polymer PEDOT. Before impregnate, usually make organic solvent like ethanol to dilute it to the range of 20~30% concentration. After impregnating and drying the core cladding, the product can enter the next process.
