Abstract
|
So far, it remains a great challenge to construct organic vapor sensor that can simultaneously achieve high sensitivity, wide detection range, and fast response. Herein, we demonstrate the fabrication of organic vapor sensor based on poly(styrene-butadiene-styrene)/carbon nanotube (SBS/CNT) hybrid fiber using the scalable wet spinning process. The SBS/CNT hybrid fiber-based vapor sensor exhibits a high sensitivity in wide workable detection range (e.g. responsivity of 19% and 256% for 10% acetone and cyclohexane vapors, respectively), rapid response time (=40 s), good reproducibility as well as excellent mechanical reliability. Moreover, such sensor can quantitatively detect the concentration of organic vapor of as low as 2% in the atmosphere. Such performances demonstrate their great potential applications in wearable and flexible electronics for VOCs monitoring.
