功能化聚乙二醇及其在制革涂饰中的应用研究进展

Research progress on functional modification of polyethylene glycol and its application in leather finishing

聚乙二醇因其优异的两亲性、柔韧性在诸多领域备受关注.聚乙二醇的端羟基具有伯醇活性,可与其他活性官能团反应来实现对聚乙二醇的功能化修饰,进而拓宽聚乙二醇的应用领域.本文综述了近年来非共价键及共价键功能化修饰聚乙二醇的研究进展,讨论了不同修饰方法对功能化聚乙二醇改性高分子材料性能的影响,介绍了功能化聚乙二醇改性丙烯酸、聚氨酯传统涂饰材料和壳聚糖等新型涂饰材料,最后展望了功能化聚乙二醇在制革涂饰材料中的应用前景.

Because of the excellent amphiphilicity and flexibility,polyethylene glycol has attracted much attention in many fields.The terminal hydroxyl groups of polyethylene glycol possess primary alcohols activity,which are easy to associate with active functional groups to form functional modified polyethylene glycol,further expanding its application range.The recent research progress on non-covalent and covalent functional modification of polyethylene glycol was reviewed,and the effect of different functional modification methods on the properties of functionalized polyethylene glycol modified polymer materials was discussed.Subsequently,the characters of functional polyethylene glycol modified polymer materials were analyzed.The functional polyethylene glycol modified acrylic,polyurethane traditional coating materials and chitosan new coating materials etc.were also explored.The application of functional polyethylene glycol in leather finishing materials was prospected.
