两性聚合物在皮革中的应用研究进展

Research Progress on the Application of Amphoteric Polymers in Leather

两性聚合物分子链结构中同时含有阴、阳离子基团,使其具有自组装特性、反聚电解质效应、pH响应性等特点,因而被广泛应用于生物医药、污水处理、皮革工业等多个领域。本文概述和分析了两性聚合物的分类、特性、合成方法及发展现状,介绍了两性聚合物在皮革复鞣、加脂及其它湿整饰处理中的应用研究进展,也对两性聚合物在皮革工业中的应用前景进行了展望。

Amphoteric polymer molecular chain structure contains both anionic and cationic groups,which makes it have the characteristics of self-assembly,reverse polyelectrolyte effect,pH response and so on.Therefore,amphoteric polymer has been widely used in biomedicine,wastewater treatment,leather industry and other fields.This paper summarized and analyzes the classification,characteristics,synthesis methods and development status of amphoteric polymers,introduced the application research progress of amphoteric polymers in leather retanning,fatliquoring and other wet finishing treatment,and also reviewed the application prospect of amphoteric polymers in leather industry.
