Abstract

Properly assembled nanostructure of hybrid materials leads to better hydrogen gas sensing performance. In this study, a nove, and facile assembly approach was developed to construct a relatively quick and sensitive conductive polymer sensor for detecting trace quantities of hydrogen gas in a nitrogen atmosphere. Through chemical polymerization, hybrid thin films of vanadium pentoxide (V2O5) and polypyrrole (PPY) were fabricated to form the ordered structure of the composites. Also, the effect of p-toluenesulfonic acid, a dopant, on the structure and properties of conducting polymer and vanadium pentoxide composite was investigated. The dopant effect was proved to improve sensing performance via a hydrogen sensing experiment. These sensors are able to detect minor current changes induced by low-coordinated hydrogen exposure (5–250 ppm) interactions at room temperature and have quick response and recovery times of 42 s and 37 s, respectively.
