摘要/Abstract

摘要：

为进一步提高氧化石墨烯在水溶剂中的稳定性,文中采用多肽聚合物对氧化石墨烯进行表面改性。傅里叶红外变换光谱和热重分析表明,两者可以通过非共价键的方式进行复合。然后,用紫外可见光吸收光谱法测定分散液浓度,表征氧化石墨烯分散液的稳定情况,并探索多肽聚合物修饰氧化石墨烯时的最佳添加量,在此基础上又探索了多肽聚合物对氧化石墨烯在水溶剂中长期稳定性的影响。实验结果表明,在氧化石墨烯浓度为1 mg/mL的条件下,当加入的多肽聚合物与氧化石墨烯的质量比为3:100时,可以有效避免氧化石墨烯片层的再次团聚,经多肽聚合物修饰过的氧化石墨烯在水溶剂中表现出良好的稳定性,且经过8周静止后也没有明显的沉淀产生。

Abstract:

In order to further improve the stability of graphene oxide in water, polypeptide polymer was used to modify the surface of graphene oxide. It was shown from Fourier transform infrared spectroscopy and thermogravimetric analysis that they can be combined by non-covalent bonds. Then, the concentration of graphene oxide dispersions was determined by UV-vis absorption spectroscopy to characterize the stability of graphene oxide dispersions, and to explore the optimal dosage of polypeptide polymers when modifying graphene oxide. On this basis, the influence of polypeptide polymers on the long-term stability of graphene oxide in aqueous solvents was explored. It was shown from the experimental results that the agglomeration of graphene oxide sheets can be effectively avoided when the mass ratio of polypeptide polymer to graphene oxide is 3:100 under the condition of 1 mg/mL graphene oxide concentration. Graphene oxide modified by polypeptide polymer exhibits good stability in water solvent, and there is no obvious precipitation after eight weeks.

Key words: polypeptide polymer, graphene oxide, composite, surface modification, agglomeration, stability
