• entirely alter their interface performance, from highly lipophilic to even lipophobic [12][13]. In turn, preparation of aqueous dispersions of CNTs requires the use of low or high molecular weight surfactants [14]. Most of the theoretical approaches concerning dispersibility of CNTs in various liquids

• , via hydrogen bonds, entangling individual CNTs. It was found recently that polysaccharides, wrapped around nanotubes, enabled their “solubility” to various levels of unbundling (rope-to-single-tube transition) [38]. The best dispersions were obtained when gum arabic was used as a natural surfactant
