The preparation of hybrid polymeric systems based on carbon derivatives with a cationic polymer is described. The polymer used is a copolymer of a quaternizable methacrylic monomer with another dopamine-based monomer capable of anchoring to carbon compounds. Graphene oxide and graphene as well as hybrid polymeric systems were widely characterized by infrared, Raman and photoemission X-ray spectroscopies, electron scanning microscopy, zeta potential and thermal degradation. These allowed confirming the attachment of copolymer onto carbonaceous materials. Besides, the antimicrobial activity of hybrid polymeric systems was tested against Gram positive and and Gram negative and bacteria. The results showed the antibacterial character of these hybrid systems.
本文描述了基于碳衍生物与阳离子聚合物的杂化聚合物体系的制备。所用聚合物是一种可季铵化的甲基丙烯酸单体与另一种能够锚定在碳化合物上的多巴胺基单体的共聚物。通过红外光谱、拉曼光谱、光发射X射线光谱、电子扫描显微镜、zeta电位和热降解等方法对氧化石墨烯、石墨烯以及杂化聚合物体系进行了广泛表征。这些表征证实了共聚物在含碳材料上的附着。此外,还测试了杂化聚合物体系对革兰氏阳性菌和革兰氏阴性菌的抗菌活性。结果显示了这些杂化体系的抗菌特性。
