| description | The invention discloses a preparation method of an adsorption photocatalytic separation multifunctional membrane based on a polydopamine bionic coating. According to the multifunctional membrane of the invention, the surface of the base film is modified layer by layer more than one time, so that the problem that the catalyst is covered or the functional particles are prone to falling off in othermodification methods is avoided, the photocatalytic nanoparticles are exposed to a light source as much as possible, the synchronous implementation of nanometer polysaccharide fiber adsorption and enrichment, GO/TiO2 catalytic degradation and membrane separation is achieved, and the efficient treatment of printing and dyeing wastewater is achieved; and compared with the method in the prior art, the preparation method of the invention is simple, easy to operate, economical, efficient and easy to industrialize.
本发明公开了一种基于聚多巴胺仿生涂层的吸附光催分离多功能膜的制备方法，本发明的多功能膜是对基膜表面进行一次以上的逐层修饰，避免其它改性方法中催化剂被覆盖或功能粒子易脱落的问题，光催化纳米粒子尽可能暴露于光源，实现纳米多糖 |
