N2 - Poly (3-hexylthiophene) (P3HT)/Au nano-islands composite was deposited on the interdigital microelectrode (IME) for the electrical conduction and gas sensing characteristics measurement. The conduction characteristic was verified to be Au nano-islands sputtering time dependent. Long sputtering time would form large-sized, closely-packed, and inter-connected Au nano-islands with irregular shape. As discussed in our previous work, there existed the mutual effects between the surface plasmon resonance of Au nano-islands and P3HT, which helped to increase the conduction. Herein, IME under 90 s Au sputtering and 60 °C heating presented the best gas sensing performance instead of longer sputtering time such as 150 s. This result implied that gas sensing characteristics of P3HT/Au nano-islands composite depended on the coupling condition between the localized surface plasmon resonance of Au nano-islands and P3HT molecules instead of the conductance characteristics.
