| Zusammenfassung: | The invention provides a diaphragm, a secondary battery and a preparation method thereof. The diaphragm comprises a diaphragm base material, a first polymeric monomer coating arranged on the surface of one side of the diaphragm base material and a second polymeric monomer coating arranged on the surface of the other side of the diaphragm base material, wherein the first polymeric monomer coating comprises a first polymeric monomer capable of being subjected to oxidative polymerization, and the second polymeric monomer coating comprises a second polymeric monomer capable of being subjected to reductive polymerization; particularly, the first polymeric monomer and the second polymeric monomer can be subjected to oxidative polymerization and reductive polymerization in a pre-charging state inwhich the first polymeric monomer and the second polymeric monomer are in contact with the positive plate and the negative plate respectively. The diaphragm can realize firm combination of the diaphragm and the pole piece by |
