Table 5: Polymer dispersant based CNM dispersions. biocompatible, cheap, and environmentally friendly dispersants. However, much work must be done on these promising materials for graphene and fullerene systems. Some of these molecules show favourable dispersion properties and superior biocompatibility over synthetic dispersants. Many of these are also more accessible and cheaper to obtain than manufactured surfactants due to their abundance in nature.
