摘要

近年来，聚离子液体在湿度传感器中的应用受到了广泛的关注。然而，在低湿度范围内，pil的离子电导率受到抑制。本研究采用疏水导电聚合物PEDOT:F制备了不连续导电模板，并在导电模板（pfctpils）上原位制备了PILs，得到了一种低湿传感器。所制备的pfctpils传感器比纯PILs传感器具有更低的阻抗值、更高的响应和更小的检测限。pfctpils传感器具有208的高响应，具有0.5 % RH的小滞后，并且在5 % -35 % RH范围内具有小阻抗值。讨论了pfctpls传感器的湿度敏感原理。

New perspective on performance optimization of polymer low humidity sensor utilizing a conductive polymer template

In recent years, poly(ionic liquid)s (PILs) have attracted much attention for the application in humidity sensors. However, the ionic conductivity of PILs is inhibited in the low humidity range. In this work, discontinuous conductive template was prepared using a hydrophobic conductive polymer PEDOT:F, and PILs was prepared in situ on the conductive template (PFCT&PILs) to obtain a low humidity sensor. The prepared PFCT&PILs sensor has much lower impedance value, higher response and smaller detection limit than the pure PILs sensor. The PFCT&PILs sensor shows a high response of 208, with a small hysteresis of 0.5 % RH and has small impedance value in 5 %–35 % RH. The humidity sensitive principle of PFCT&PILs sensor has been discussed.
