Sensors/Biosensors: Nanocomposite of Nitrogen‐Doped Graphene/Polyaniline for Enhanced Ammonia Gas Detection (Adv. Mater. Interfaces 16/2019)
Nicolas R. TanguyMohammad ArjmandNing Yan
Abstract
Combining polyaniline and graphene doped with nitrogen favors the formation of electrical heterojunctions in the nanocomposite. During exposure to ammonia gas, the concurrent immobilization of charge carriers by dedoping of polyaniline and increasing depletion layer depth causes a more pronounced change of the electrical resistance of the nanocomposite as compared to pristine polyaniline. Further details can be found in article number 1900552 by Nicolas R. Tanguy, Mohammad Arjmand, and Ning Yan.
