A gas nanosensor unaffected by humidity.
نویسندگان
چکیده
The fabrication of a gas nanosensor for detecting ammonia gas in air that is unaffected by humidity is demonstrated. On functionalizing single-walled carbon nanotube (SWNT) networks with a precise amount of camphorsulfonic-acid-doped polyaniline (PANI(CSA)), the opposite electrical resistance responses of the CSA-doped PANI and SWNTs to humid air effectively canceled each other, thereby eliminating any effects of humidity during sensing experiments. The approach should be widely applicable for eliminating undesirable interferences for gas nanosensors.

Intercalated graphitic carbon nitride: a fascinating two-dimensional nanomaterial for an ultra-sensitive humidity nanosensor.
We develop a novel humidity nanosensor based on intercalated graphitic carbon nitride (g-C(3)N(4)) nanosheets fabricated by a facile thermal polymerization of common urea in the presence of LiCl as the intercalated guest under air and ambient pressure. The response and recovery times of an optimal nanosensor can reach ∼ 0.9 s and ∼ 1.4 s, respectively, which are superior to most of the traditio...
