摘要: 多酚与金属离子形成的金属-多酚网络(metal-polyphenol network,MPN)能发挥金属与多酚的协同效应,既具有金属离子赋予的特定功能,又具有多酚结构对各种表面的高亲和力,能吸附在纳米材料和生物界面等多种表面上,且结构更加稳定。近年来MPN发展迅猛,在很多领域都得到了广泛的应用。本文首先概述了MPN的组装机制和组装原材料(主要是单宁酸和铁离子),简要介绍了一步共混沉积法和层层组装法两种组装方法及常见的表征方法,详细论述了MPN的抗菌性、抗氧化性、吸附性和pH值响应性等功能特性及其在食品领域的应用等,并对MPN的未来发展趋势进行了展望。

Abstract: The metal-polyphenol network (MPN) formed by polyphenols and metal ions combines the specific functions of metal ions and high affinity of polyphenol structures to various surfaces synergistically. MPN can be adsorbed on various surfaces such as nanomaterials and biological interfaces, with more stable structure. In recent years, MPN has developed rapidly and been widely used in many fields. This article summarizes the assembly mechanism and components (mainly tannic acid and iron ion) of MPN, and briefly introduces readers to the common assembly methods of one-step blending deposition and layer-by-layer assembly, as well as the common characterization methods. Particularly, the antimicrobial activity, antioxidant effect, adsorptive property and pH response of MPN are discussed, with focus on its application in food field. Finally, this article gives an outlook on future trends in the development of MPN.

Key words: metal-polyphenol network; film; tannin acid; iron ion
