Abstract

Superhydrophilic zwitterions have been extensively exploited for surface modification to improve antifouling properties. However, it remains challenging to form layers of < 20 nm with high zwitterion content on the surfaces with different degrees of hydrophilicity. We demonstrate that amine-functionalized sulfobetaine (SBAm) can be co-deposited with dopamine on ultrafiltration (UF) membranes, leading to a thickness of 10 nm to 50 nm and an SBAm content of up to 31 mass% in the coating layers. The covalently grafted SBAm is stable underwater and improves the antifouling properties, as evidenced by the lower trans-membrane pressure required to retain targeted water fluxes than that required for the pristine membranes. The SBAm is also more effective than conventionally used sulfobetaine methacrylate (SBMA) for the zwitterion grafting on the surface to improve antifouling properties.

摘要

超亲水两性离子已被广泛用于表面改性以改善防污性能。然而,在具有不同亲水性程度的表面上形成具有高两性离子含量的小于20 nm的层仍然具有挑战性。我们证明,胺官能化的磺基甜菜碱(SBAm)可以与多巴胺共沉积在超滤(UF)膜上,导致涂层厚度为10 nm至50 nm,SBAm含量高达31质量%。共价接枝的SBAm在水下稳定并改善了防污性能,这通过保持目标水通量所需的跨膜压力低于原始膜所需的跨膜压力来证明。对于表面两性离子接枝以改善防污性能,SBAm也比传统使用的甲基丙烯酸磺基甜菜碱(SBMA)更有效。
