论文名称:Ultrafast, Highly Sensitive, Flexible Textile-Based Humidity Sensors Made of Nanocomposite Filaments 发表刊物:Materials Today Nano 关键字:SWCNT; PVA; Humidity Sensors; Textile Sensor; LiCl 摘要:Wearable electronics are promising next-generation smart textiles for human-computer interaction, health monitoring, and other applications. However, integrating electronic functions into strong, highly deformable electronic textiles and maintaining their functionalities during wear is a great challenge. Herein, we report ultrafast, highly sensitive, textile-based humidity sensors made of single-walled carbon nanotube (SWNT)/polyvinyl alcohol (PVA)/lithium chloride (LiCl) nanocomposite filaments fabricated via a wet-spinning and a solvent exchange process. The SWNT/PVA/LiCl textile-based humidity sensors exhibited excellent stabilities during deformation and high sensitivities with 6-fold resistance variations over a wide range of relative humidity (RH) conditions. The ultrafast responses of the sensors were attributed to the quick deliquescence of LiCl during contact with water molecules and the simultaneous conductivity change caused by the generated ions. The as-prepared sensors responded well to human breathing and real-time humidity changing, which could distinguish different breaths and microclimate change. Such outstanding sensing performances of our textile-based sensors in combination with their mechanical flexibilities enable the facile integration of high-performance humidity sensors onto textile substrates for real-time microclimate monitoring. 全部作者:Youngseok Oh,Byung-Mun Jung,Moon-Kwang Um,Sang-Kwan Lee,Tsu-Wei Chou 第一作者:Zuoli He 论文类型:期刊论文 通讯作者:Gengheng Zhou,JungIl Song,Joon-Hyung Byun 学科门类:工学 一级学科:环境科学与工程 文献类型:J 卷号:18 页面范围:100214 字数:8000 是否译文:否 发表时间:2022-05-01 收录刊物:SCI 发表时间:2022-05-01
