AuNPs monolayer doping Poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT : PSS) film on interdigitated electrode had been fabricated into AuNPs/PEDOT : PSS Janus film sensor to detect hydrogen sulfide (H₂S). The results show that the Janus film sensors have a wide measurement range of H₂S concentration. The sensitivity of PEDOT : PSS/AuNPs sensor grows up with the thickness of Janus film increases. The resistance response of AuNPs Janus film was affected little by the rough surface states of PEDOT : PSS film. In addition, the PEDOT : PSS/AuNPs film sensor had been used again to detect H₂S. This work presents a platform to inspire a novel high sensitive chemiresistive sensor via nanoparticles monolayer.

金纳米粒子单层掺杂 PEDOT：用于硫化氢传感器的 PSS Janus 薄膜

AuNPs单层掺杂聚（3,4-亚乙基二氧噻吩）：聚苯乙烯磺酸盐（PEDOT：PSS）膜在叉指电极上制成AuNPs/PEDOT：PSS Janus膜传感器以检测硫化氢（H ₂ S）。结果表明，Janus 薄膜传感器具有较宽的 H ₂ S 浓度测量范围。PEDOT 的灵敏度：PSS/AuNPs 传感器随着 Janus 薄膜厚度的增加而增大。AuNPs Janus薄膜的电阻响应受PEDOT：PSS薄膜粗糙表面状态的影响很小。此外，PEDOT : PSS/AuNPs 薄膜传感器再次被用于检测 H ₂ S。这项工作提供了一个平台，通过纳米颗粒单层激发新型高灵敏度化学电阻传感器。
