| description | The invention discloses a preparation method of a PI film for ion separation. The preparation method comprises the following steps: vertically and uniformly irradiating the PI film in vacuum through a heavy ion accelerator; the irradiated PI film is sensitized through ultraviolet light, the PI film is taken out after sensitization, organic fragments in the PI film are cleaned out, then the PI film is naturally aired, the sub-nano porous PI film is obtained, and straight through holes are formed in the sub-nano porous PI film. The preparation method is simple and practical, the sub-nano porous PI film has a high ion separation ratio, a good separation effect and stable performance, and the application range of the sub-nano porous PI film is widened, and industrial production is facilitated.
本发明公开了一种用于离子分离的PI膜的制备方法，包括以下步骤：通过重离子加速器在真空中对PI膜进行垂直均匀辐照；通过紫外光对辐照后的PI膜进行敏化，敏化后取出并清洗出PI膜内有机碎片，然后自然晾干，得到亚纳米多孔PI膜，该亚纳米多孔PI膜上形成有直通孔。本发明的制备方法简单实用，亚纳米多孔PI膜具有较高的离子分离比，分离效果好且性能稳定，有利于提高其应用范围和进行产业化生产。 |
