一般描述

聚乙烯亚胺（PEI）是一种具有直链或支链结构的正电荷聚合胺。它可与多种金属离子螯合。它高度溶于水并在水溶液中用作有效碱。由于其优异的理化性质，它被广泛应用于生物医学、水净化、生物成像、基因传递和自愈材料中。

应用

聚亚乙胺溶液可用于阳离子交换树脂的表面改性。改性树脂可提高过渡元素的选择性。由于阳离子层内的排斥效应，对碱性离子的选择性会有所降低。结果表明，这种树脂可通过柱吸附用于工业业废水的净化。

它可作为前体，制备聚电解质多层膜，以促进细胞在植入物表面的附着和生长。

PEI可在水介质中制备金属纳米粒子时用作反应性模板和稳定剂。PEI中的氨基团可以与溶解于水的金属离子配位，并降低其聚集能力。这会导致形成更小的纳米粒子。

特点和优势

  • 它具有重复结构单元和柔性聚合物链。
  • 由于PEI上存在大量的氨基团，因此可以对其进行修改或功能化，以获得特定特性，如敏感性、特异性和生物相容性。
  • 高水溶性。
