For first stages of nanomaterial production, it SB 415286 is highly significant to choose a suitable solvent which can effectively prevent products from being bundled or cluster-assembled. ILs and DESs have been widely used as efficient dispersants during the synthesis reaction of nanoproducts. They have played roles in determining the shape, size and morphologies ,  and . They are also capable of splitting small-scale structures into nano-scale and this aspect is added to their use as a functional dispersing solvent. Many examples of graphene-ILs hybrids fabrication, obtained by using ILs solvents for carbon nanotube (CNT) or graphite exfoliation, support this case  and . After nanomaterials production, ILs may be used to form nano-hybrids (i.e. nanofluids or nanocomposites) in order to enhance special properties of the nanomaterials in the mixture or get the mixture itself ready for certain application. However, in spite of the large number of articles discussing the dispersibility of nanomaterials in ILs, the reported cases of using DESs for the same purposes are still few in comparison, but one gene are existed at least. The aim of the following sections is to cover and summarize all relevant cases available so far for different DES dispersing purposes.
