| titleOfInvention | A kind of ammonia gas sensing film based on HPTS and hydrotalcite nanosheets and preparation method thereof |
| abstract | The invention discloses an ammonia gas sensing film based on HPTS and hydrotalcite nanosheets and a preparation method thereof. The film is made by solvent evaporation of three components, HPTS, hydrotalcite nanosheets and polyvinyl alcohol. Among them, hydrotalcite nanosheets and polyvinyl alcohol immobilize and disperse HPTS molecules, reducing their vibration and rotation, making them exhibit excellent fluorescence properties. The ammonia gas sensing film prepared by the invention has good light transmittance and film-forming property. Compared with the HPTS aqueous solution, the ammonia gas sensing applied to ammonia gas shows a wider linear detection range and a lower detection limit, and the detection limit can be Up to 0.1‑0.01ppm, and the film has excellent reproducibility, fluorescence performance, and light stability. |
