一种金属酞菁接枝改性PVDF中空纤维膜的制备方法
摘要：
本发明专利涉及膜分离材料技术领域，具体为一种金属酞菁接枝改性PVDF中空纤维膜的制备方法。本发明通过清洗商品PVDF中空纤维膜；然后再配制多巴胺溶液；再在PVDF中空纤维膜表面涂覆多巴胺溶液；最后将四氨基钴酞菁与三聚氯氰反应合成出四(2,4‑二氯‑1,3,5‑三嗪基)氨基钴酞菁，接枝到PVDF中空纤维膜即可。
摘要（英）：

The invention relates to the technical field of film separation materials, in particular to a preparation method of a metal phthalocyanine graft modification PVDF hollow fiber film. The method includes the steps of cleaning a commodity PVDF hollow fiber film, preparing a dopamine solution, coating the surface of the PVDF hollow fiber film with the dopamine solution, finally synthesizing cobalt tetra(2,4-dichloro-1,3,5-triazine)aminophthalocyanine by making cobalt tetraaminophthalocyanine react with cyanuric chloride, and grafting cobalt tetra(2,4-dichloro-1,3,5-triazine)aminophthalocyanine to the PVDF hollow fiber film.
