General description
聚乙二醇(PEG)是一种人造生物相容性惰性聚合物,由醚氧(-CH2-CH2-O-)重复单元构成。可通过氧乙烯的阴离子聚合反应制得。因具有非免疫原性和高水溶性,广泛用于生物和医学领域。
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.
Application
聚乙二醇可用于修饰磁铁矿纳米粒子。在磁核上涂覆PEG外壳可使纳米粒子在保持磁性的前提下具备良好的稳定性。
PEG可用于修饰光催化TiO2纳米粉末,用于制造自清洁涂料。PEG涂覆的TiO2纳米粉末可通过温和条件制备,具有优异的胶体稳定性。
可用作交联剂,制备基于聚N-异丙基丙烯酰胺的热敏型可注射水凝胶。引入PEG提高了水凝胶的化学和机械性能,防止水凝胶在溶胀介质中溶解。这种水凝胶由于生物相容性和生物可降解性,广泛用于生物医学领域。
