一般描述
聚乙二醇（PEG）是一种亲水性聚合物。它可以通过环氧乙烷的阴离子开环聚合反应而进行合成，产生不同的分子量和端基。当交联成网络时，PEG可具有高含水量，形成“水凝胶”。聚乙二醇（PEG）不会引发免疫反应，是一种理想的生物学应用材料。
应用
聚乙二醇(PEG)可与非离子表面活性剂吐温80共同官能化修饰磁性纳米颗粒。聚乙二醇官能化可增强磁纳米颗粒的生物相容性。还能降低表面电荷，维持纳米颗粒的磁性。
聚乙二醇可用作药物最终剂型的外部包衣，为原料药提供防潮保护。例如，drop printing（液滴打印）技术可使聚乙二醇包覆在萘普生固体分散体上。PEG包衣可保护固体分散体，避免潮湿导致的结晶加快，并增强稳定性。
以聚乙二醇作为有机改性剂，通过溶胶-凝胶技术可制备纳米结构的羟磷灰石(HAP)。聚乙二醇可影响羟磷灰石形态。高温下，柔性更高的聚乙二醇分子形成更大的羟基磷灰石片。低温下，柔性较低的聚乙二醇胶体形成纳米结构的羟磷灰石。
聚乙二醇还可作为泻药使用。
