摘要: Abstract In this work, polythiophene (PTh) nanoparticles were successfully deposited on poly(ethyleneterephthalate) (PET) substrate as thin film by a facile and rapid chemical oxidative deposition method using binary organic solvent system in the presence of N-cetyl-N,N,N-trimethylammonium bromide (CTAB) cationic surfactant. The electrical conductivity PTh PET was optimized adjusting surfactant/oxidant/monomer molar ratio, monomer concentration time polymerization. Resulted conductive, transparent flexible which can be used electronic devices such OLEDs. Electrical for un-doped at oxidant/monomer ratio 5:1 0 °C polymerized 12 min measured to 1.18×10−2 S/cm. effect oxidant polymerization yield also investigated. structural confirmation transparency nanoparticle coated films characterized FTIR UV–vis spectroscopy, respectively. Field emission scanning electron microscopy (FESEM), laser particle size analysis transmission (TEM) employed surface morphology distribution measurements nanoparticles. results showed that are globular aggregates with average about 50 nm PET.
