基于RGO-PEO复合薄膜的QCM湿度传感器研究
Research of QCM humidity sensor based on reduced graphene oxide-polyethylene oxide composite films
摘要
Abstract
A reduced graphene oxide (RGO)-polyethylene oxide (PEO) composite film was constructed on quartz crystal microbalance (QCM) by air spraying with composite and bilayer film structures for ambient humidity detection. The morphology and chemical properties of the fabricated pure PEO film and RGO-PEO composite materials were characterized by SEM and UV-Vis spectroscopy. The addition of RGO into PEO film contributes to a remarkable enhancement in dynamic response and sensitivity (34.7Hz/%RH) compared with the pure PEO film (16.3 Hz/%RH). Furthermore, RGO-PEO composite film based sensor holds rapid response and recovery rates (3 s and 4 s @63.2%respectively), which is better than those of pure PEO based sensor (10 s and 12 s@63.2% respectively), negative hysteresis (1.21%RH) and excellent long term stability. This research reveals the promising potential of RGO-PEO composite film based QCM sensors in the humidity detection at room temperature.关键词
