Progress on Development of Surface Grafted Polyethylene Glycol（PEG）Brush

摘要: 聚乙二醇(PEG)刷能形成压制细菌靠近、产生排斥渗透力、降低聚合物链段运动性的高亲水性层,可阻止蛋白质的非选择性吸附以及减少细菌和微生物的粘接,可提高基质表面的防污能力,对金属而言亦可增加其缓蚀性能。本文综述了聚乙二醇刷在聚合物、硅基材料和金属等材料表面的应用,并提出了聚乙二醇(PEG)刷在未来应用于非生物金属材料防污及防腐等方面的可能性。Abstract: Polyethylene glycol(PEG) brush can form a highly hydrophilic layer on the material surfaces to prevent the non-selective adsorption of proteins and reduce the adhesion of bacterium and microbes for its repulsive penetration.The anti-fouling applications of poly(ethylene glycol) brush on polymers,siliceous materials and metal surfaces are reviewed and the possible application on metal surface for anticorrosion is covered.
