A novel WO x -EDA nanowires/PEDOT/PSS hybrid material was successfully synthesized by a convenient two-step method. The diameters and lengths of WO x nanowires were 50-200 nm and 10-30 mm, respectively. SEM and TEM images proved the good interaction between PEDOT/PSS and WO x nanowires. Their gas sensing properties, studied at room temperature, exhibit a good sensitivity (»6.76), a fast response (»18 s) to 10 ppm NH 3 , and an excellent detection limit. The new material has a better sensitivity than that of WO x nanowires towards NH 3 , which might be attributed to a synergetic interaction between PEDOT/PSS and WO x nanowires.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
