摘要
本文通过第二单体甲基丙烯酸二甲氨基乙酯(DMAEMA)将石墨烯分散到甲基丙烯酸甲酯(MMA)中制成石墨烯/MMA分散液,分别以第二单体甲基丙烯酸二甲氨基乙酯(DMAEMA)、乙烯基三甲氧基硅烷偶联剂(KH-171)、单烷氧基类钛酸酯偶联剂(JTW-101)为分散助剂将石墨烯分散到苯乙烯(St)中制成石墨烯/St分散液。通过沉降实验、离心实验、偏光显微镜、X射线衍射(XRD)、傅里叶变换红外光谱(FTIR)和拉曼光谱等对石墨烯/MMA和石墨烯/St分散液的分散情况进行分析和研究。实验结果表明:石墨烯已被均匀、稳定地分散于MMA或St中;以第二单体甲基丙烯酸二甲氨基乙酯(DMAEMA)为分散助剂制备的石墨烯/MMA分散液分散效果最好。
In this paper, the graphene was dispersed into methyl methacrylate （MMA） with the aid of 2-（Dimethylamino） ethyl methacrylate （DMAEMA）, the second monomer, and the graphene/MMA dispersion liquid was obtained. The graphene was dispersed into styrene （St） with the aid of 2-（Dimethylamino） ethyl methacrylate （DMAEMA）, the second monomer, vinyl trimethoxy silane coupling agent （KH-171）, or monoalkoxy base titanate coupling agent （JTW-101） as dispersing agent, and the graphene/St dispersion liquid was obtained. The dispersion of graphene/St and graphene/MMA dispersion liquid was analyzed and studied by the subsiding experiment, centrifugation experiment, polarizing microscope, X ray diffraction ~XRD） and Fourier transform infrared spectra ~FTIR）, and Raman spectrum. The results show that： graphene has been dispersed evenly and stably in MMA or St. The MMA/graphene dispersion liquid was prepared with the aid of 2-（Dimethylamino） ethyl methacrylate （DMAEMA）, second monomer, as dispersing agent was the best.
