开发了一种使用离子液体聚合物（PIL）作为转移介质生产溶液相可转移石墨烯片的实用路线。发现用PIL修饰的化学转化的石墨烯片对化学还原是稳定的，并且良好地分散在水相中而没有任何团聚。在石墨烯片上的PIL的阴离子交换后，水相中的这些PIL改性的石墨烯片通过将它们的性质从亲水性改变为疏水性而容易地转移到有机相中。
A practical route to the production of solution phase transferable graphene sheets using ionic liquid polymers (PIL) as a transferring medium is developed. Chemically converted graphene sheets decorated with PIL were found to be stable against the chemical reduction and well dispersed in the aqueous phase without any agglomeration. Upon the anion exchange of the PIL on graphene sheets, these PIL-modified graphene sheet: in aqueous phase are readily transferred into the organic phase by changing their properties from hydrophilic to hydrophobic.
