This is the first demonstration of the feasibility of using the interaction of paramagnetic sites of mechanochemically nanostructured graphite particles with aliphatic alcohols (ethanol and octanol) to change the properties of graphenes formed in the liquid-phase exfoliation of thus modified samples of nanostructured graphite. The presence of various functional groups was confirmed spectroscopically. Raman spectroscopy was used to show that treatment of mechanochemically nanostructured graphite with alcohols may lead to graphenes with fewer defects. The graphene nanoparticles from the resultant dispersions have a tendency to agglomerate upon the removal of the solvent, which increases due to the presence of functional groups on their surface.

机械化学纳米结构石墨与水和脂肪醇相互作用制备的改性石墨烯

这是首次证明利用机械化学纳米结构石墨颗粒的顺磁性位点与脂肪醇（乙醇和辛醇）的相互作用来改变在纳米结构石墨改性样品的液相剥离中形成的石墨烯的性质的可行性。光谱证实了各种官能团的存在。拉曼光谱用于表明用醇处理机械化学纳米结构石墨可能会导致石墨烯具有更少的缺陷。来自所得分散体的石墨烯纳米颗粒在去除溶剂后有聚集的趋势，由于其表面存在官能团，这种聚集趋势会增加。
