One-dimensional poly(3,4-ethylenedioxythiophene) (PEDOT) nanomaterials, were fabricated via chemical oxidation polymerization in reverse (water-in-oil) microemulsions, including ellipsoidal nanoparticles, nanorods, and nanotubes. Cylindrical micelles were prepared with sodium bis(2-ethylhexyl) sulfosuccinate (AOT) and aqueous iron(III) chloride solution in an apolar solvent. The morphology of the final products was determined by carefully tuning the degree of oxidation potential at the micelle surface. Gram-scale products were obtained under an optimized synthetic condition, suggesting that our methodology was appropriate for the large-scale production of the corresponding nanomaterials. The as-prepared PEDOT nanomaterials were applied to the precise detection of alcohol vapors. The chemical sensors based on the PEDOT nanomaterials presented excellent reversibility and reproducibility in response. |
