一般描述

聚环氧乙烷（PEO）2是一种高分子量、非离子水溶性聚合物。它在水化时形成凝胶，并具有良好的膨胀能力。EPO聚合物无毒，广泛用于药物递送系统以改善药物可溶性。

应用

聚环氧乙烷可用于制备：
  • 用于药物缓释的可生物吸收、可注射水凝胶。
  • 用于燃料电池的PEO/氧化石墨烯复合电极膜。
  • 聚环氧乙烷-b-聚ε-己内酯（PEO-b-PC）二嵌段共聚物。内含氯沙坦钾的（PEO-b-PCL）共聚物可用作药物载体。

Polymeric hydrogels long have attracted interest for biomaterials applications because of their generally favorable biocompatibility. High in water content, they are particularly attractive for delivery of delicate bioactive agents, such as proteins. However, because they require covalent crosslinking for gelation

We report on the preparation of drug nanocarriers by encapsulating losartan potassium (LSR) into amphiphilic block copolymer micelles, utilizing the biocompatible/biodegradable poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) diblock copolymer. The PEO-b-PCL micelles and LSR-loaded PEO-b-PCL nanocarriers were prepared by organic solvent evaporation method
