| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
