摘要
研究了一种制备两性离子聚合物修饰的抗菌氧化石墨烯(GO-PSBMA)的方法.基于氧化石墨烯(GO)表面含有大量的-OH,采用酯化反应制备了具有大量溴引发位点的GO(GO-Br).使用甲基丙烯酸磺基甜菜碱(SBMA)作为聚合单体,通过表面引发的原子转移自由基聚合(SI-ATRP)在GO-Br表面进行聚合.用聚合物改性的GO对大肠杆菌表现出99.99%的抗菌活性.本研究有效地建立了对氧化石墨烯的新型聚合物改性方法,赋予其优异的抗菌性能.
Abstract
A method for preparing antibacterial graphite oxide(GO-PSBMA)modified by zwitter-ionic polymer brush was studied.GO(GO-Br)with a large number of bromine initiation sites was prepared by esterification based on the large amount of-OH on the surface of graphene oxide(GO).Methacrylate sulfobetaine(SBMA)was used as the polymerization monomer and polymerized on the surface of GO-Br by surface-initiated atomic transfer radical polymerization(SI-ATRP).GO modified with polymer brush showed 99.99%antibacterial activity against E.coli.A novel polymer modification method for graphene oxide was effectively established,which endows it with excellent antibacterial properties.
