Abstract: A preparation method of a collagen material stripped from an electrode and a use of the collagen material are provided. The preparation method of a collagen material stripped from an electrode includes the following step: subjecting a collagen solution including hydrogen peroxide and/or acetic acid to electro-deposition (EDP) to obtain the collagen material on the electrode. The preparation method can lead to a collagen material directly on a surface of an electrode.
