abstract: Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) incorporated with nanocrystalline TiO2 (PEDOT:PSS+nc-TiO2) and silver nanoparticles (PEDOT:PSS+AgNP) films were prepared by a spin-coating technique. AFM and FE-SEM surface morphologies, UV-Vis spectra and NH3 gas sensing characteristic of the composite films were studied. The results showed that the PEDOT:PSS+nc-TiO2 film with a content of 7.0 wt.% of TiO2 is suitable for both the hole transport layer and the NH3 sensing characteristic. The response time of the sensor made from this composite film reached a value as fast as 30 s. The rapid response to NH3 gas could be attributed to the efficient movement of holes as the major charge carriers in the PEDOT:PSS+nc-TiO2 composite films. Useful applications in the organic electronic devices like light emitting diodes and gas thin film sensors can be envisaged.
