The present invention provides a method for preparing a polyion thin film (in particular a polyion thin film with different surface morphologies) and the polyion thin film prepared by the method. The method comprises: providing a substrate, and coating a first lubricant on a surface of the substrate or on a surface of a tinfoil covered on the surface of the substrate; covering a film-forming liquid of the polyion thin film on the surface of the substrate with the first lubricant, and after coating uniformly, covering a cover plate coated with a second lubricant on the film-forming liquid; performing a polymerization reaction of ionic liquid monomers in the film-forming liquid to form a polyion thin film; and separating the polyion thin film and cleaning it to obtain the polyion thin film. The polyion thin films with different surface morphology can be prepared. The present invention further provides a detection kit.
