A 3D porous P4VP film prepared via breath figure (BF) is used for quaternization to synthesize humidity‐sensitive polyelectrolytes. By combining the BF method, gaseous crosslinking, and screen‐printed electrodes, humidity sensors with good stability and a fast response to humidity change are obtained, thus making them possible for application in human breath monitoring. The water molecule adsorption of the porous polymer under different RHs is investigated using a quartz crystal microbalance. Cole–Cole plots and ionic conductivity change show that these devices function as humidity sensors under different humidity atmospheres.

基于呼吸图法的基于3D多孔聚电解质的湿度传感器

通过呼吸图（BF）制备的3D多孔P4VP膜用于季铵化以合成对湿度敏感的聚电解质。通过结合BF方法，气态交联和丝网印刷电极，可以获得具有良好稳定性和对湿度变化快速响应的湿度传感器，从而使其可用于人类呼吸监测。使用石英晶体微量天平研究了多孔聚合物在不同相对湿度下的水分子吸附。Cole-Cole图和离子电导率变化表明，这些设备在不同的湿度气氛下都可以用作湿度传感器。
