Twistable and tailorable Cu-doped SnO2@PANI textile for wearable ammonia sensing

In Situ-Polymerized PANI/WS2 Nanocomposites for Highly Sensitive Flexible Ammonia Gas Sensors and Respiration Monitoring Devices

“…In particular, PANI is favored due to its excellent conductivity, ease of synthesis, low gas-sensitive test temperature, and excellent compatibility with flexible substrates. − While PANI is promising for preparing flexible NH 3 sensors, there are some drawbacks, including low sensitivity compared to conventional metal oxides, poor long-term stability, and not having a fast enough response/recovery time, which are obstacles to preparing flexible sensors. To address the problems with pure PANI, researchers have combined carbon-based nanomaterials or metal–semiconductor-oxide nanomaterials with PANI to improve gas-sensing properties, including improved conductivity, enhanced sensitivity, and an extended range of sensor applications. , …”
