| titleOfInvention | Composite membrane and preparation method and application thereof |
| abstract | The invention discloses a composite membrane and a preparation method and application thereof, wherein the method comprises the following steps: mixing the fullerol with a silane coupling agent and then dehydrating to obtain fullerene modified by the silane coupling agent; preparing an alkaline solution of fullerene modified by a silane coupling agent; depositing an alkaline solution of the silane coupling agent modified fullerene on the substrate to form a first thin film; and depositing the metal oxide nanoparticle solution on the first film to form a second film, and combining amino or sulfhydryl on the surface of fullerene on the surface of the first film with surface metal elements in metal oxide nanoparticles on the surface of the second film at the combined interface of the first film and the second film to prepare the composite film. The invention not only can reduce the preparation cost of the gas sensor, but also can further improve the selection performance of the gas sensor. |
