Beschreibung
Zusammenfassung:	The invention discloses a Ni@NiO@ZnO@CS composite metal wire for copper ion detection and a preparation method thereof. The composite metal wire comprises a Ni metal wire, a NiO nano layer formed by oxidizing the surface layer of the Ni metal wire, a ZnO nano flower cluster uniformly coating the surface of NiO, and a CS film uniformly distributed on the ZnO nano flower cluster. The preparation method of the composite metal wire comprises the following steps that a thermal oxidation method is used, and thermal oxidation is carried out in a tube furnace to prepare the NiO nano layer by taking the Ni metal wire as a substrate; a hydrothermal method is used, and the ZnO nano flower cluster is grown on the NiO nano layer by taking Ni@NiO as a substrate; and a physical impregnation method is used, and a CS film is wrapped around the surface of ZnO by taking a Ni@NiO@ZnO composite metal wire as a substrate. The method has the advantages of being simple in process, mild in reaction condition,low in preparation cost a
