摘要：

为制备灵敏度高的柔性湿度传感器,以更适合可穿戴使用场景,提出以聚对苯二甲酸乙二醇酯(PET)为柔性衬底,在其上制作叉指电极,然后以聚乙烯吡咯烷酮(PVP)和多壁碳纳米管(MWCNTs)为原料制备溶液,通过静电纺丝技术将MWCNTs/PVP沉积在柔性PET衬底上制成柔性湿度传感器。借助扫描电子显微镜对薄膜的微观结构进行表征和分析,并通过设计的实验装置对传感器的线性度、响应/恢复时间、重复性和稳定性进行测试。结果表明:该柔性湿度传感器的输出电阻值与相对湿度呈现良好的线性关系,线性相关系数为0.97,可检测的相对湿度范围为40%~90%,响应时间为20 s,恢复时间为5 s,在75%相对湿度下经40次重复测量,传感器表现出良好的重复性和稳定性。

Abstract:

In order to prepare a flexible humidity sensor with high sensitivity and more suitable for wearable use scenes, polyethylene terephthalate (PET) was used as a flexible substrate for making interdigital electrodes, and polyvinylpyrrolidone (PVP) and multi-walled carbon nanotubes (MWCNTs) were employed as the raw materials to prepare the spinning solution, and MWCNTs/PVP was deposited on a flexible PET substrate by electrospinning technology to make a flexible humidity sensor. The microstructure of the membrane was characterized and analyzed via the use of scanning electron microscopy, and the linearity, response/recovery time, repeatability and stability of the sensor were evaluated using the designed experimental devices. The results show that the output resistance of the flexible humidity sensor has a good linear relationship with the relative humidity, and the correlation coefficient is 0.97. The detectable relative humidity range is 40%-90%, the response time is 20 s, and the recovery time is 5 s. After 40 repeated measurements under 75% relative humidity, the sensor shows good repeatability and stability.
