Based on existing industrial knowledge and equipment, liquid exfoliation is probably the most viable option for expanding graphene practical application fields. The method’s principal attraction is a scalable process where pristine graphite is subjected to a solvent treatment enabling the creation of graphene dispersion suitable for end applications without transition processes. The challenge is that graphene has a limited disperse ability even in solvents suitable for it, which is due to its small mixing potential and strong π-π attraction between twodimensional graphite structures. The article discusses the possibilities of using an organic biodegradable solvent derived from natural cellulose residues Cyrene (dihydrolevoglikosenone) as a base solvent to create a liquid graphite exfoliation medium. Since the objective of obtaining graphene dispersion suitable for textile surface modification was not achieved, triethanolamine was added as a result of the search for solutions to improve the performance of the liquid medium. Several technological sequences have been developed and a comparative analysis is presented based on stereomicroscopy observations, micrographs, graphene flakes lateral dimension analysis and evaluation of dispersion adhesion intensity on the fibres of para-aramid fabric.
