摘要
多巴胺(dopamine)是一种生物神经递质,在水溶液条件下,它能在溶解氧的作用下发生氧化-交联反应,形成强力附着于固体材料表面的聚多巴胺复合薄层.基于多巴胺的这一特性,近年来膜技术研究者们通过多巴胺在固体基膜上的自聚-复合,对膜进行表面改性,并以具有反应活性的聚多巴胺复合层为平台,对膜进行进一步的表面修饰,实现膜的功能化.文章论述了多巴胺在膜表面修饰与功能化方面的研究进展,应用领域包括超/微滤膜、生物医用膜以及渗透汽化膜等.
Dopamine is a kind of biological neurotransmitter. In aqueous solution, it can be oxidized by dis solved oxygen and undergoes an oxidation-crosslinking reaction, forming a composite layer of polydopam ine that strongly attaches to a substrate. Based on the characteristics of dopamine, in recent years, membrane technology researchers have performed surface modification via the self-polymerization-composite of dopamine on solid basement-membranes. Besides, the polydopamine composite layer with high reactivity offers a platform for further surface modification and functionalization. In this paper, research progress on modification and functionalization of membrane surface using dopamine was reviewed, the application fields included ultra/micro filtration, biomedical membranes and pervaporation film, etc.
