摘要自2004年后，首次证明石墨烯单片在普通环境下的稳定存在，石墨烯得到了蓬勃的发展，很多科研人员对其产生了浓厚的兴趣。而石墨烯单体又存在诸多问题，而经过改性的氧化石墨烯性能较好，所以本次实验就是对氧化石墨烯改性的研究。本实验首先是通过氧化石墨烯的酰氯化（让经过超声分散的氧化石墨烯与氯化亚砜反应得到）再与β－环糊精（β－CDS）在70℃和100℃酯化反应得到功能化的氧化石墨GO-CDS。通过FT-IR，XRD，TGA分析确定环糊精（CDS）已在GO上，使其的晶体结构完整性降低，热稳定性升高。又做了功能化氧化石墨烯的分散性对比试验，结果证明功能化的石墨烯分散性得到了加强。本次实验又做了氧化石墨烯/PEG聚合物复合材料的制备，并做了TG测试，得到的结论是复合材料的热稳定性得到了加强。59870

Title Preparation and properties of the functionalized  graphene  derivatives

Abstract

Since 2004, the graphene chip in the general environment is stable for the first time demonstrated and graphene has been vigorous development, many researchers developed a keen interest in them. However, there are many problems in graphene monomer, and after modified graphene oxide performance is better, so this experiment is to study graphene oxide modified. This experiment was that let ultrasonic dispersion graphene oxide react with thionyl chloride and then react with β-cyclodextrin (β-CDS) at 70 ℃ and 100 ℃ to get graphite oxide functionalized GO-CDS. By FT-IR, XRD, TGA we analysis to determine the cyclodextrin (CDS) was at the GO, the integrity of the crystal structure reducede the thermal stability increased. I made the comparative test that the dispersion of the functionalized graphene oxide, the results prove the dispersion of functionalized graphene oxide has been enhanced. This experiment has done a graphene oxide / PEG polymer composites, and do a TG test, the conclusion that the thermal stability of the composite material has been strengthened.
