| 摘要 |
Embodiments described herein provide for gas detectors and methods for their preparation and use. Some embodiments provide for a gas detection film including an insulating base layer, a conducting layer including a plurality of conductive clusters having a known degree of percolation below a percolation threshold; and a non-conductive reactant layer between the insulating base layer and the conducting layer. Some embodiments described in this document also provide for methods of making a gas detection film, methods of detecting a detectable gas, and kit for detecting a detectable gas. In some embodiments, the detectable gas may include mercury vapor, water vapor, formaldehyde or a combination thereof. |
