“…These solvents have to have high dielectric constants and very low solubility in the hydrocarbon solvents in order to form structured aggregates [8]. The most common polar solvents used include formamide (FA), dimethylformamide (DMF), dimethylacetamide (DMA), ethylene glycol (EG), propylene glycol (PG), and glycerol (GY) [9][10][11][12][13][14][15][16][17][18][19][20]. Most of these studies have been focused on phase diagrams [5], viscosity and conductivity behavior [11], and dynamic light-scattering measurements to determine micellar sizes and intermicellar interactions [12,13,15].…”
