Polyaniline@SnO2 heterojunction loading on flexible PET thin film for detection of NH3 at room temperature

- Rapid synthesis of PANI has novelty, which is different to that reported before.
- SnO2 enhances the response of PANI by their complementary and synergistic effect.
- PET film is used as substrate to obtain a flexible, wearable and smart sensor.
- Room temperature operating of sensor leads to save energy, safety and long life.
