Ammonia is increasingly deemed a significant, green sustainable fuel

which requires a large number of detection devices. In this study,

ultrathin AuNWs/PEDOT:PSS Janus films had been prepared with ultrathin

AuNWs film treated with H2S which could integrate with PEDOT:PSS film

closely. The resulting transparent and flexible Janus film sensor showed

the good response and selectivity performance to ammonia gas. Moreover,

the sensitivity of Janus film devices to ammonia was greatly improved

and the conductivity of the Janus films was kept well with increasing

thermal annealing temperature. The limit detection for NH3 was 500 ppb

concentration and the improvement mechanism of the sensing performance

was attributed to the increased surface area of conductive polymer. This

method provides a universal platform to integrate different materials

into Janus films and prepare next-generation flexible detection.

sensors.
