Fast response ammonia sensor based on porous thin film of polyaniline/sulfonated nickel phthalocyanine composites

- PANI/NiTSPc composites were deposited on interdigitated Au electrode.
- The response value of the film to 100 ppm NH3 was 2.75 with a response time of 10 s.
- The performance results from the thin-film structure and the “NH3-capture” effect.
